The murmurings on the board seemed to point in the direction of the 26 and 27 breaking in quicker than the heavier weights when it came to the j3a. I don't know if it was true or not, but I didn't care for the 28oz j3a. When I decided to try a 2014 juggy, I went with a 27oz, just to test that theory. I actually really like the 14 juggy, so who knows Could all be in my head.
