No, I try to flatten my hand out. It may be my fault, but sometiems when I am sure it was flat it still seems to not wuite hook, just roll a little the way I didnit intend for it too. It's hard to explain its reaction.
But, that ball can hook!!! When I crank it on even light oil that thing will turn the corner!
