hahaha so awesome.
like i said above...all my sticks are center ( i have 8 pair) but dont bother with the lizzies they kick ass at reccomended...i had this same questions with mine and the shop told me to take their demo pair out with is a recc. i did and that's that. they rule.
In case you've never ridden these if you don't do recomended it will be harder to lay down turns. The recomended is spot on with this ski. Any more forwards and its gonna be a super washy tip and any more back and good luck landing jumps.
Just mount it at recomended
