Achey wrists are pretty standard, because on a trials bike your weight lies a lot further over the front of the bike than any other non-trials bike. At 5'10 your not massive for a mod, I'm 6 foot and have ridden loads of short frames, (monty ti 07, 05, adamant short X2, Koxx XTP 05 short and probably a few others) I found them a tad uncomfortable but liked how they rode, best for you to nabb other people bikes on a ride try it out, if your dead into TGS i would suggest getting a barge, I loved the 2 KO MK1 longs I had, and love the feel of the older Pythons like the baby pitbull is perfect!
