Yeah, my neck has been bothering me lately and I've recently figured out I have osteoarthritis. After about an hour of riding my neck would start to bother me. I considered Helibars but opted to order the more fully adjustable Convertibars. I opted for the complete kit with longer brake, clutch and throttle lines. I'll try to document the install as well. Stay tuned!
Let us know how it goes. I put the Genmar risers on mainly because I wanted to retain the stock look as much as possible and they really did help despite being rather small. I never had back/neck problems while riding but my hands would start to hurt. I used to be done after 2 to 3 hours but don't really have as bad an issue anymore. Those convertibars should provide you with some relief.
