As 'harsh' as it sounds, unless someone has tested different height bases on the same bike under identical conditions, who really knows that there is a quantifiable difference?

And when would that difference come into play?

Example,,, Bruce, I believe, is the only one (I think) who went to a base ~1~ inch taller than what he originally had,,, All the rest of us, I believe, are running the same height base we have always had.

And, just using Bruce as an example, what base he likes the best may not be the base that works for someone taller/smaller/wider - whatever.

I'm sure that a base 'several inches' higher would have some different characteristics than another, but unless I'm mistaken, there is no more than about ~1 1/4~ inch difference in height between the all the F6B bases currently in use. Those like mine, ~8~ inches of exposed base from top of shield to top of rubber strip or the one like Dshark w/ ~9 1/4~ inches of exposed base from top of shield to top of rubber strip (10 to bottom of strip)

Anybody with less or more?
