Kind of picky here, as you might have suspected!

I've got a knee that bugs me if the seat isn't adjusted exactly so. I carry Allen wrenches in case I need to adjust the post during a ride.
That seatpost reminder doohickey is a good idea, but I tend to change saddles frequently as I'm on a Holy quest for one that I can ride for 4 hours without consequence!
