I'm like you, Kirsten...in that I sometimes get that "pinching" of the labia on the cutout of my Ruby. Which is why I opted to try out the Affinity RXL, which I ended up returning today.
I loved riding in the drops on the Affinity, because it offers a tad bit more padding on the nose over the Ruby. Riding in my drops on the Ruby is pretty painful (for me), because there is next to nothing in the way of padding on that nose. I can generally only last about a minute or two before I have to come back up on the hoods. On the Affinity, I could stay in the drops for a good 5 minutes...woo-hoo!
BUT...after 400 miles of testing, my sit bones were just not happy on the Affinity...thus, the reason for returning it. Up next on my list...the SI Turbomatic.
