To twist the pouch don't eliminate the handslap. Maybe, to do it reduce a little the problem, but if you shoot a 5/16 steel with a TBG 1" straight, there is a big handslap risk even if you twist.
Always I twist the pouch but sometimes I get handslap when bands are not matched with the ammo.
Even I don't agree with your opinion about TTF as style for noobies. Think the most people begin with OTT style because it is more common, easier to align and aim, while TTF is more difficult to align and it has more risk of fork hit.
