Re: selespeed = trouble ???
from ppl i know, selespeed isn't unreliable. but once in awhile, issues do crop up. but these are the exceptions than the norm. but like all systems, they will wear out. a good gauge may be abt 100k.
as for fun factor, having tried it b4, its so much like driving a manual car minus the left foot. imo, a manual is still the way to go as i can use heel and toe, and i like my left foot to be working. feels wierd without it. & of cos, the cheaper repairs are a great bonus!
