I held out and used Veloflex corsas all winter - they're fairly cut up but still usuable after a lot of winter riding (including some accidental CX) but they feel so much better than GP4000s that it felt worth the extra cost.
I also felt much more confident in the wet on Corsas than GPs, two cents from another idiot
Just had a look on the veloflex website where it says they can be inflated up to 145psi (compared to 120 for GPs) which may well be worth it for the track
