5.0 out of 5 stars
Bombs Away!, April 25, 2011
This review is from: Easton SRV5 Salvo Slow-Pitch Softball Bat (Sports)
The purpose of my review is two-fold--both to give you a sense of this bat (Easton Salvo) and to to help you make a good decision on a bat, whatever you choose. The Salvo is my favorite bat.
I purchased an Easton SRV5 "Salvo", 26 oz bat. This bat is appropriate for players ranging from full sized "big guy" types to 110 lb women players. I can hit bombs with it. The weighting and pop of the bat have allowed women on our team to get nice line drives to the outfield. If you are a "beast", or have played semi-pro ball, or your friends affectionately call you "meat", you may want to move up to the 28 oz or 30 oz versions of this bat. The 26 oz version is quite adequate to drive the ball 300 feet from a standard slow pitch.
There is little real information out there about bats, especially considering how much they cost. I started looking at composites because I felt like a Luddite hitting with my old aluminum bats. Looking around my league (a relatively laid back co-ed rec league), it is surprising how many people are hitting with $200 to $400 composite/hybrid bats. I bought the bat at a local store because I personally found it hard to figure out which bat is the best without actually swinging the darn things. I put my review on Amazon, because you may have a hard time finding this bat by just shopping.
Bats currently have many specific markings on them that seemed impenetrable to me.
Most bats have two key marks on them.
1. BPF = 1.20
2. ASA certified (ASA 2000, ASA 2004, or ASA 2009) and/or some other association USSSA, ISF, NSA,
These are the same on super cheap bats and on expensive composite bats and don't really tell you much about how the bat will perform, except that it meets some standard--more in a second.
Why composite?
The main reason to purchase a composite bat is that the performance generally will be better than the best aluminum bats. This has been shown experimentally by folks such as Prof. Daniel Russell at Kettering University, the Sports Science Laboratory at Washington State University, and there is even information on this on the Lance Armstrong's "Livestrong" foundation website (I have no idea why they care about softball bats).
Back to the Salvo... It also has the following markings: 1) barrel 12 in. 2) USSSA 1.20 BPF, 3) NSA Approved, 4) ISA Approved, 5) 98 MPH, 6) ASA Certified 2004, and 7) ISF 2005 Certified. Also, the bat is covered by two patents--look these up if you want the nitty gritty on the bat. USPTO 6,866,598 "Ball bat with a strain energy optimized barrel" and USPTO 6,764,419 "Composite baseball bat having an interface section in the bat barrel"
Q. Why so many darn markings?
A1. To keep people (mostly pitchers) from getting killed. Literally.
A2. There are many different associations trying to control bat performance.
If you play high end softball, many pitchers wear the equivalent of a catcher's or hockey goalie's mask. This is to keep pitchers from getting hit and injured by batted balls. The pitcher's mound is ~45 feet away from the plate. A ball hit at 98 mph (which very good hitters can do) reaches the pitcher in about 0.3 seconds, very close to the fastest possible human response time. It is possible to make bats that hit balls much faster than 98 mph. To control this, softball and baseball associations require that bat performance be measured and that conforming bats be marked appropriately. That said, there are really only two major standard out there.
1. ASA 2004, 98 mph performance-The ASTM F2219 test = "ball-in, ball-out"
The ASA test is meant to simulate the exit speed of an approved softball that is thrown at 25 mph and hit by a (very good) batter swinging the bat at 85 mph. To do this, they fire a ball at a stationary bat at 110 mph (= 85 mph + 25 mph) and measure the exit speed (a "ball-in, ball-out" test). The maximum allowable exit speed is 98 mph. The ASA 2004 stamp means that the bat gives 98 mph OR LESS in the exit speed test. So, low and high performing bats all get the same ASA stamp if they pass this test. I play in an ASA league, so I needed an ASA approved bat. The Salvo is ASA approved.
Easton is unclear what "98 mph performance" means. It implies that the Salvo gives a 98 mph exit speed in the ASA test, since they make a non-ASA bat (Easton Synergy Tri-Zone SCN18) that is not ASA certified and lists a "100 mph performance" mark.
2. BPF 1.20--Currently, the standard for USSSA, ISF, NSA, and ISA-The ASTM F1890 test = "ball in, bat out"
BPF is supposed to measure the springiness of the bat. The actual calculation is pretty complicated and is covered on the WSU website. Again, a ball is fired at a stationary bat, but this time the rebound of the bat and ball are measured.
The ASA standard seems harder to meet than BPF = 1.20--there are many BPF 1.20 certified bats that do not meet the ASA 2004 standard. Most peer reviewed work seems to prefer the ball-in ball-out test as being more realistic. Also, the ASA is now working to test bats that have been broken in rather than new bats.
Breaking in a composite bat improves its performance.
The performance of composite bats gets better as they are used. After somewhere between 500 and 1000 batted balls, the composite will have become less brittle and more elastic. This flexibility helps spring the ball off the bat better and results in faster batted balls. You can break in a bat by using it, or there appears to be a whole cottage industry of artificially breaking in bats using specialized vises with rollers.
There is also an industry of "juicing" bats by putting them in a lathe to reduce weight and improve springiness. I will suffice to say this is a bad and actually dangerous idea.
Field testing the Salvo
Went out last weekend and hit standard Rawlings ASA approved 12" balls off a stationary tee. I routinely could hit shots that I measured >260 feet. From a pitched ball, these would be significantly farther. I was pretty amazed. Really.
Cons? The knob is really small. I taped the end to make it fatter so I wouldn't lose my grip and could swing harder.
What Weight? Can you bench 300 lbs? If not, the 26 oz bat will be great. Lighter weight = Faster swing speed = faster ball exit speed = longer hits. If you are huge, get the bigger bat (28 or 30 oz).
p.s. the P90X DVD is one of the best non-equipment routes to improve your performance. Your core (torso) turns out to be very important for hitting.
