I went with the riser extension kit from Scootworks for my V2K with a Corbin, adds just enough pullback and a little more rise. I angled the bars back down a hair, allows me to rest back against the Corbin Dual Tour seat without reaching, but doesn't bring the bars too far back( I'm 5'10"). I think they were a good option, and much less $$$ than complete new risers.
