I'm throwing mainly fairway drivers from the tee right now and my most effective driver right now is a 167g TP Hatchet.
Hyzer flips are my preferred way to throw.
Given this info^^^
I have a few recommendations, (coming from a guy near 60 with similar pains).
I don't think you're going to get easy distance by going up in speed and more flippy, from my experience, going down that road is more frustrating.
Take a look at some 150 class stuff, yeah, it's not the greatest in the wind, but you'll learn how deal with it. Besides, you probably already have heavier stuff to deal with the wind when you feel the need.
150 class stuff will also help you to throw smoother and cleaner and can make a world of difference with those aches and pains.
Some 150 class discs I bag and have had real good luck with;
Star and Star-lite Sidewinders and Roadrunners
Air Escapes and Underworlds
The Jade! An easy Hyzer flip machine
Inertia
DX Teebirds and Eagles
And my fastest disc I carry, Star-lite Wraiths. These can really bomb and do well in average wind.
Try some 150 class stuff, it will help you throw cleaner and your body will thank you in return.
Best of luck
