Started out throwing RHFH because of a blown out right knee from playing racquetball earlier in my life, so it's normal for me. I watched the DC forehand driving video with Mark Ellis and noticed the forehand throw in disc golf is almost the same motion as a racquetball forehand drive shot.
My home course also favors sidearm with a lot of dogleg right holes. Everything went along fine until I started playing other courses which favor RHBH and I got frustrated.
About five months ago, I got a knee brace for the bum leg and started practicing BH throws. The accuracy is finally coming around but I'm still 70-100' short of my FH shots. My backhand averages about 260-280' now with most of them going right up the pipe. I figure if I work on accuracy first, the distance will come as my form improves.
What really helped me the most with my weaker BH was digging out my old retired slower discs which I overpowered as my forehand power increased.
I've had to rearrange the drivers in my bag totally. Now, about a third of my discs are high speed FH drivers, a third slower BH drivers and a third overlap which I use for both FH and BH.
My goal is by the end of the year to be able to throw my backhand accurately over 300' on demand. There's still a lot of work to do but I feel a lot more confident now about my game as I am no longer a one arm bandit.
Now if my right knee will hold together just a little longer!!! That reminds me, I have to go ice it down now. LOL
