Welcome Creeture3
Mate I would like reccomend someone like John Moorehouse (Brisbane), but like a lot of other well regarded motorcycle seat trimmers, he sets you up for an optimum riding position and not how you cope when stationary.
If, as I read you are vertically challenged, be aware the more foam that is removed in order to bring ya bum closer to terra firma, the broader the seat becomes and
may compromise holding the bike steady by the steat digging into an inner thigh.
I'm on the Gold Coast at present, but live in Sunbury, so when I get home your very welcome to try my low cut Corbin, to experience what I saying.
Cheers the can :-)
