You tire choice: explain this

I’m another Attack/Force and/or GP4000S II, most GP4000S II on my TT bike.

I run the Continental Grand Prix tires on my road bike where I log most of my bike miles… Black Chili compound tire.

Why do I use them, readily available, great specs and IMO the industry leader for real reasons.

I’ve used Vittoria and Michelins, wasn’t a fan due to quality, wear characteristics and a few other things.
