Review of blades is a subjective matter. I can compare barwell fleet to acoustic, both equipped with tibhar mx-s (backhand) and mx-p (forehand), 2mm. Barwell is noticeabley better in blocking, also better touch at the net - lower gear. Acoustic is too springy with the mx-p. It's harder to keep the ball short at the net with the acoustic and on smashes it's got a lot of catapult. Barwell fleet has a lower gear at the net and less max speed with the mx-p on smashes, but it is easier to generate mid range power. On backhand, mx-s with the acoustic has great spin, but power is very low and on flat hitting it's really dead. With barwell fleet there's less spin, but it's easier to generate power, easier to lift, easier to block. I was probably heading to serious elbow problems with the acoustic, barwell fleet makes the game easier, it's almost criminal how easy and controllable it is. I thought acoustic was great, but barwell fleet gives me a better range of shots, blocking is superb. I hear people complain about blocking with BF - forgive them father for they do not know what they say. My game went up a notch instantaneously after switching from acoustic to BF. Better control, better range of speed, easier to generate power, great stability, blocking. It's a masterpiece.
