Do the front swap. Your reason was the exact same as mine was and the reason for my change. I went from a full Firebolt and swapped to a Lightning body (still retained the R harness) with stock Lightning bars. I soon figured out that the stock bars While sitting me up more and taking the pressue off my wrist now put my wrist in a position that agrivated my Tunnel Carpal. I swapped the stock Bars to a semi agressive Renthal Ultra Low bar and it was like a whole new bike. There was no Presure on my wrist and the Down angle/pull back on the bars releaved the numb feeling in my right hand. As of Now Im using CR Clubman bars. Some will argue that im back to where I started, But thats not the case. Even Though Im back to my aggressive seating position the CR Clubman bars are a diffrent pull back and down angle than the stock Firebolt.......Thus making me and my wrist very happy.(I'm going for less stress on my wrists)
Few pics of my bike and its transormation over the last couple of years.......
Day I bought it.

After swap with stock bars
Rental Ultra Low bars.....notice they are slightly lower and not pulled bac as far on the ends
CR Clubman bars...
Palces you just a bit further fowards than the Firebolt but the egros on the wrist are way better.
I know its alot of pics.....im just trying to show as best I can the diffrent changes I went through. As my bike sits now Im Happy.
