My backhand has taken over and now I need to practice forehand just so I can throw it accurately.
Me too. I have only been playing for a few months, but pretty quickly decided that I needed to work on my backhand if I wanted to get good at this game.
My sidearm was easy from the get go, backhand much more difficult, especially for distance.
I had thrown a lot of catch discs and realize that my good technique from those was not great for golf.
Mainly, sidearm distance is easy without doing any footwork. You can just do a weight shift to your front (left) foot while throwing sidearm and get close to your Max D. With backhand I had to force my self to throw with my weight off my right foot, to really get my weight forward. In other words, the place in a sidearm throw that was balanced for release was not correct for backhand.
There are two main ways I can see from my recent experience to start throwing backhand, either with drivers that require a lot of nose down (the high speed drives you have listed), or with putters, midranges, and older drivers. I'd recommend not using the high speed drivers at first, but gradually mix them in.
Why? Besdies the fact that this is Blake's standard advice
Because it was easier for me to really feel my balance and weight shift when throwing backhand from a low position to a high one, really snapping the wrist with a hyzer release. With high speed drivers, this technique will lead to more stall outs and a feeling that you aren't getting anywhere. But once it feels clean, it is just a 15 minute adjustment to do the same thing with the wrist in a nose down position.
Going the other direction, from practicing with high speed drivers to then standing over a 150 foot roc shot, for me at least was frustrating as I didn't really know how to throw firm and clean with 40% power.
Good luck. Expect a few shanks and griplocks. But know that you can go from 200 to 290 very quickly, Then once at 290, other things start to kick in and it becomes fun to see how far you can push that drive.
