I'm sorry for you guys, it's BS how much you guys pay for rubbers!
Here are some pics of how my Exedra Max is coping with my apparently aggresive riding style:
It's front and rear edge of the same groove. You can see "slight" cupping behavior but it's not at all bad considering what this tire has dealt with and how hard I've been punishing it for the it's first 700 miles. It's wearing great!!
Here's my Cobra front after about 2500 miles:
Also coping pretty well. You can see minimal cupping and it's still smooth and grippy as hell, totally confidence inspiring using these two together and very very good grip.
