^^at least be honest about how little fun you're having DWing on a 6m in 17kn on a boat of a board.
Even a 75kg mate of mine who rides surfboards, and well, uses his 8m neo from 15 to about 20 and then changes to his 6m. Sick kite from low to late 20s, but would rather be on smaller again at solid late 20s to 30kn.
If you ride a foil from 15kn and then a variety of boards all with your 6 then fair enough, but say so. Can't imagine any (other) shop recommending a 6m neo as one kite for that wind range. It's silly.
Ps. I ride neos
