What do youo think is the best drive system

[sparky]

Has anyone tried hooking up through an internal (shimano/Sturmey-Archer/others) 8 speed internal hub? Apx 300% hi-to-lo ratio, in equal steps...

People have done it, but I don't think they've been as reliable as the NuVinci seems to be. Plus, if you wanna do it right, you have to stop pedaling or giving it gas due to the way internal gears work... can't shift on the fly as well as derailers.

P.S. - Sturmey-Archer 8spd doesn't have even stepping really. It's pretty awkward.
