A guy I play with has spent the last few months throwing LHBH as well as RHBH. He only does the LHBH on open holes, but can get it out further than RHBH. The consistency isn't really there yet, but on open/long holes it definitely helps him get some extra D.
I don't feel i need to try, since i can use RHBH, RHFH, RHBH turnover shots, so i don't think it would add much (other than less shoulder fatigue, which would be good for my screwed up shoulder from pitching all those years)
I throw Yellow and white Prodigy/Innova/DGA discs.
