I had an opportunity to compare the Bontrager Affinity RXL to the Inform RL last weekend. The channel in the Inform is longer & deeper than the Affinity. The Inform provided great sit bone support & gave my girly bits a lot of room. The Affinity also provides great sit bone support but squishes my bits more than the Inform. I'll post more about my experience with the 2 saddles after I do an apples to apples ride comparison.
