In my opinion, they aren't race-worthy. Assuming yours are similar, I expect you'd notice a difference. Do you notice a difference between them and the Michelins? To try an expensive tyre, I usually just buy one and put it on the front. The only tyre I was blown away by was the Vittoria Open Corsa KS. The GP400s have had great reviews.
Yep, that looks like them.
I couldn't really compare them to the Michelins cos they were on a new bike that I was getting used to so I never really pushed them (and I ditched them after getting too many flats). I've actually had a Michelin on the back for the last couple of races... wouldn't have known it though for all the difference it made.
The differences in bike tyres seem more subtle than motorbike. I used to race on Michelin, but if you switched them to Dunlop, I'd know by the first corner (hehe... I'd be on my arse).
When you say not race-worthy, is it because of rolling resistance or grip? Mine haven't fallen apart like yours did.
