One of my friends throws LHFH and RHBH. For some reason he can't get a LHBH going. This leaves him with the problem of only having left fading shots.
I've seen more lefties developing right handed shots than the other way around. Probably because lefties learn to use their right hands for all the stuff that isn't ambidextrous. I can't do a darn thing lefty. I've tried to throw, but just can't get anything going. I've got both a RHBH and RHFH going, so no real reason to worry about it, I guess.
