One question: i thought a side arm throw produces less spin in general that a backhand throw, which explains why they turn over more easily than backhand throw? is this not right? Also, my side arms improved greatly after reading this sites article on side arm. The big different for was:
*Two fingers together under rim, with middle finger touching rim and index finger stacked on or laying against middle finger. The grip seems to promote the palm up orientation needed in this throw. Before this, i had two finger tips on rip, which created inconsistent throws.
*Elbow fairly close to body, but not touching. If too close, isn't this called "rexing" the throw.
*I've never thought about an x-step with this throw. I'll have to try it. By the way, why can't we all call the x-step the tango step? It's almost the same (sorry, I've been learning the tango lately).
