>>Gel seat rocks.<<
I took a tip from a fellow duane here and picked up an AirHawk seat. All I can say is "WOW"! I can ride pretty much indefinitely with this thing, thanks duane!
What's great about the AirHawk is that you can just throw it on any bike, so you if you have more than one bike or if you get another bike, you can continue to use it. They make different sizes, some for the pillion seat, so you may want to consider one for your daughter if she's still uncomfortable with the new gel.
