I've ridden the '05 byerly a couple sets and it's much improved. My buddy, who has ridden it for about 6 months now kills it on that skate. He hits his 180 shuv-its with more consistency than he ever did on his Concave Cassette.
I was riding the older 107 just the other night and tried a shuv-it to board slide on the wake...the edge dug and board flipped like a potato chip on only a very slight chop.
