don't forget the monkey butt powder.

Having the seat cut for your butt makes all of the difference in the world.  A generic seat is meant to fit a generic rear, which none of us have.  They'll therefore have spots where too much weight is resting, which cuts off circulation, pinches nerves, makes you tired and uncomfortable.  I had a quickie cut on my GS500 seat just to make the stock foam fit my behind, and also shelled out for a fitted cut with a gel pad for the commutermobile.  I didn't do anything to the SV seat, since by butt is off of it as much as I can manage.  But I did a 400-mile trip (yes, I know, kid stuff) on the GS the day after getting it cut, and it was all good and happy.  I'm going to post a writeup of the fitting of the Breva seat to the OT board, FWIW.
