I'd just go for the team with the best looking kit. Here's why:
Climbing test in full CSC kit:
Duration: 12:12 (12:16)
Work: 235 kJ
TSS: 21.7 (intensity factor 1.034)
Norm Power: 351
Climbing test in jean cut offs and old Lynard Skynard T-Shirt:
Duration: 12:12 (12:16)
Norm Power: 311
It's pretty clear that looking cool is worth a bit more than 10% NP. Considering the amount of money spent on tiny improvements, it's clear that paying for your kits is a great power/cost value, if they are eye candy.
