Now that sounds like a nice way to be... leggy
I'm 5'10 and 29" inside leg ('Posterior Quackus' for me to then), can manage my 12 GSA on both low and standard seat. the only problem with the low seat is its fecking uncomfortable over a distance much more than 150 miles and my ar*e it dead... used the standard seat on a run up to Assen earlier in the year with full luggage and enjoyed it loads more. The suspension on the 12GSA is very slack... my tip, stand it up-right and then apply the front break, when you lean it back over on the side stand you loose a good couple of inches on the seat height and hence getting on is much easier...
My other tip...
Daytona Boots
I've got a set of Trans Open GTXs that I got them to increase the sole thinkness on, the only issue is they could do with more of a boot heal on them.
The M Star and Lady Star boots are good, as they both have a 2.5" rise in the heal, you can't see it from the outside, but it does mean you can get your foot down comfortably... only problem is they are very limited on sizes.
The only down side to all of this is I have managed to drop my 12GSA now once on either side, though I was no where near it on the 1st occasion.
