Well All I have used is the mapam controls. I realy liked them on the 750 spirit.
I cant comment on any of the other options out there. but I plan on buying some for the VTX as soon as I can.
Not sure what Shadow you ride exactly, but here's the setup on my Shadow Spirit 750:
Custom World International Highway Pegs. They didn't quite give me the stretch that I wanted so I ordered up some Scootmods forward controls on the cheap. If everything works out right I'll be able to keep the Highway Pegs with the new setup.
Just got the stuff from Scootmods, haven't had a chance to mount them yet cause of the snow, but they look like solid parts.
