I've recently changed my game significantly by tailoring my bag to my game instead of trying to match my game to the discs in my bag. I've done a lot of field work recently to refine my throwing style and improve my form. A lot of people on here have suggested taking some videos to help you review your throwing motion, and I can't stress the importance of that enough. It really helped me figure out my style.
I started off playing disc golf as a predominantly RHFH thrower. I grew up playing baseball and felt like I had the best power and control throwing this way. I became very comfortable with hyzer, anhyzer, and control shots, but I felt like I was missing out on a completely different dynamic of the game by pigeonholing myself this way. I put in a lot of time to figure out a proper RHBH throw, and my scores have dropped significantly. I've had a lot better luck with slightly US discs for my RHBH throws. I've had great success with my Daedalus, Sidewinder, Leopard, Colossus, and Monarch when throwing backhand. I use my OS discs as forehand discs because I have better control and can get a lot of power with an anhyzer throw. My Destroyer, Wraith, Orc, and Tern have been my dominant forehand discs.
However, these guys are right, driving will soon become the easy part of your game, wait until you get serious about putting. I work with 4 different putters to try and figure out what works best in whatever situation I find myself in. Long story short, keep your discs, work your game, figure out the right discs for you and you'll be a lot less frustrated when you get out on the course.
