I have not had a chance on the 13 ones yet, but definitely recommend the 12 over the 11. The 11 was too wild for me. I mean I guess my threshold is lower than a lot, but for the the 12 though it kept the wild streak it felt a lot more controllable in the gusty conditions I ride.
I think the 14 meter of the 11 was good tho. The smaller was too aggressive for me. The 12 were still aggressive, and totally annihilated me a few times, but felt like it was my fault if you know what I mean.
Looking forward to checking out the 13 tho.
