I'm about to buy either the vaporfly flyknit 4%s or the next%s and I can't decide which to buy. The flyknits are significantly cheaper (in the realm of $50) cheaper but I understand that the next% provides better protection against rain and moisture. I'm leaning towards the flyknits because they're cheaper, but I'm concerned that if I race on a rainy/wet day, they'll soak up water, get heavy, and place me at a disadvantage. Can anybody comment on their experience using the flyknits in wet conditions?
