Gear Vendors or swap for performance 5 spd OD?

Depends on what your looking to accomplish. I have a car that I converted to a 5 speed and one that has a 727 and a GVOD. If I had it to do over again on the 5 speed car I would have bolted the GV behind the 833. Why? Less to no mods to the car that take time and money.
The gear splits sound nice but under race conditions I doubt they will work. I mainly just use my GV as an overdrive gear.
