I'll use it Andre, when switching up to set up a diff look counter. I used to switch up alot more then I do know, but did it fairly regularly. Just switch quickly, jabbing with the right in the process (soon as left foot is behind obv), more as a range finder to set up a hard straight left/overhand/or left hook while moving both backwards and to the right. That prob sounds more complicated then it really is. I suppose it could be dangerous, but it never really gave a lot of probs as do it going backwards before a pivot to engage the left.

Dunno. I think if you spend a lot of time working out of both sides in sparring the transition becomes less dangerous and more natural.
