I need to have a taller backrest for the wife when we start riding in the spring. I'll go with the HD tall backrest and a compact pad if I have to but was hoping for something more like the backrest you have on a dyna. Small pad not the big pad of the touring models. Can I put a smaller dyna like pad on a touring backrest? My wife is petite and just wants more back support from the stock short backrest that came on my 08 SERK. Any ideas?
