My stock MK3 has 13.4 and I'd never go back to the shorter length. Used to ground early, now it doesn't. Two up particularly was no fun. Steering is quicker, but not at all twitchy, so that's better. Center stand is not an issue, I consider it a + that the bike almost jumps up on the center stand by itself. True, the back tire lightly touches the ground so I use a 1/4 " piece of plywood under the stand if I want to free up the wheel or once on the stand you can rock it to right, stick a piece under the left leg and visa versa. The inconvenience with the center stand is more than offset by the benefits gained with a longer shock.
