As for my wifes arm, not a lot of progress, so I'm going to have to ride with my oldest all summer


Getting your wife off the XT will likely be the best thing you did for her riding skill. Heavy, poorly suspended bikes are not a girls friend at all. Light, well suspended and powerful enough for their riding style...the only way to fly. With my wifes short stature and light weight, I had/have very few choices....The KX 100 and CRF150R being the 2 top choices, 3rd a KDX with a lowering link, but it's not ideal for her (for me...of course). After riding the R, I'm glad we got that one. It's so agile, I don't know how she could go wrong with that bike.
