So, I decided to try the whole "flex" concept with the football shaped saddle. Turned out good, but I have to say, I dont think anything is gained over the original design. When flexed, it does change the dynamics of the adjustable bridge loops as well. I think its the angle the bottom webbing that makes the difference. The regular football shape does a fine job of cupping when in the sitting position, so the added material of the pleat is kind of lost. If your a long time sitter, then it might be good for you.
