Have had Alpha 10s/12s and the BT003s. The Supercorsas (not the same as the Diablos you have there) were better than both by far in my opinion. They are more expensive though.

It really depends on your riding though. If its all or mainly road then Supercorsas may not be ideal, in which case my opinion would be the Rossos. I've always liked Diablos.

Just my opinion..
