Uni.
Racing against Terry & Kris, I stayed with them in the 1st race (light air) but in the 2nd the wind picked up to 10-11.
My thinking is that the A class has done an awful lot of experimenting with mast/sail comibnations. Not so much experimenting with the F16 uni.
Did you happen to notice Kris picked up three 3rds at GYC? What, she's been driving a year now?
