Did 33 miles today and the shorts felt good. I like the chamois a lot and the rear only elastic waistband felt great. I have an organized metric in a week and a century the week after so I will try them out on the longer distances but Im pretty sure they will become my favourite shorts for longer rides.
Good luck with your short shopping.
The most effective way to do it, is to do it.
