I've started using one, mostly to keep all the plumbing
functional as per manufacturers specifications. I must
admit, the elastomers really do soften the ride, and the
centerline cut out keeps everything working as it should
with no nether regioin numbness.
I was on a Fizik Arione, which I liked with regard to sit-
bone comfort more than this, however, now that I have the
saddle more dialed in, I am coming to love the PRS, and
coming home from a 4 hour ride with a fresh back and not
feeling beat up by the road.
Its a little heavier than the arione, but given the
alternative its no comparision.
