If that's the case like you mentioned 7.5 for waves and the 10.5 punch for tt. It pulls like a 12 but depowers nicely to feel like my smoke. Just about indestructible I've ridden ozone and cabrinha and in my opinion the rabbits are heaps better.
Good luck
Agreed, I ride wainmans 7.5 & 10.50 , canopies are bulletproof line quality has been my main issue, broken 2 bridles and three quickrelease lines within 12 months, replacements are very expensive, rip off would be an understatement.
