Am happy to report that we now have a Selle Italia Max Flight on the road bike (so all 3 bikes now have cutout saddles) and there seems to be marked improvement after even just a few days.

YYYYeah Selle Italia As a bonus, he now has a white saddle/white handlebar tape on his road bike JUST like I have. Coincidence? I think not....

Thank you everyone for the help! And why why why do they even sell the other non-cutout kind?
