Hi LittleSeki, if I recall correctly there have been suggestions to try to adapt your technique to alleviate stressing your wrist. That's what I tried, and it works for me. I also train people with wrist and hand injuries (tendons, mostly); some of them wear hand or wrist braces when playing for additional support.
They don't play with bricks, but then again, pretty much nobody does; just regular stuff, somewhere around 185g, and balanced pretty much according to personal preference. Mine is pretty low, certainly for a spin-based player.
If you need light rubbers, you can do much worse than Coppa. If you are indeed inclined towards a balsa blade — a hitter's blade rather than a spinner's blade — that sounds like a proper match to me. Then again, equipment will likely not alleviate physical issues that much, unless you also change your stroke mechanics.
