I played with the standard classic grip originally, but at one point when I ramped you my practice time significantly I developed wrist and forearm problems that became permanent, forcing me to switch to pipers grip, and give up other things like playing guitar and mandolin

My suggestion would be don’t mess with what’s working. Sure, you’ll probably be fine if you change your grip, but there’s still a slim chance it could cause problems, and I’m evidence the problems can be permanent.
That said, playing pipers grip means having very few options in the used flute market, which really sucks

so there’s that to consider for sure.
That's exactly the thing I was worried about. Were you certain that your classic grip was optimal? It seems like a thing that could easily put more strain on something if you were a slight bit off. I noticed that when I rotated the head joint that it was suddenly much easier and more comfortable to use the classic hold, since I wasn't trying to roll the flute back so much to get my lips to line up with the embouchure hole.
If I can get to the same level with a modified key configuration, it sounds like that'd be the way to go. It would definitely limit secondhand options, but I only need one good flute, and I'm saving for one right now.
