I didn't mean picky as to the material. I used to play a lot of ball hockey wayyyy back in Grade school. I always used abs as well, but you have to realize that abs are pretty much limited to ONE curve type per brand... the only brand i found that had a couple of cruves to choose from were the old vector abs blades. I don't know if they make it anymore but they were good and were not only for ball, but roller and ice too.
they are much lighter than the traditional koho crossovers or the "big curves".
what curve are you looking for anyways? i know abs curves, even when stamped a certain players name, are different than the carbon ones... even wood curves are different.
for ball hockey, i remember it didnt make a difference because no matter what your bakchand will never be hampered by a big curve. Flatter curves would be ideal in stickhandling and control since the ball flies.
