Agreed, but the unintentional consequence of my tush feeling better is appreciatedLest we forget, the purpose of suspensions is not to provide a smooth ride to your tush, but to keep the tires in contact with the road.
A bike like that is intended to make you feel good on the inside, not the outside (Same reason many ride a Ducati...)

Knifey, any updates??
