I ride mine about an inch back from the front of the tracks on both my KT 42 and 62 liter boards with the 1240, 1040, or 914. I find it keeps the swing weight really consistent. I do not adjust for different conditions, I let my body adjustments deal with more and less power in the wind or waves. When I rode Naish boards (50L and 75L) I rode them in the same forward in the box location.
Thanks for the feedback Solo.
In flat water, that's where I normally ride mine. But with swells, I find that I have to keep too much pressure on my front foot when I gybe onto the swell. Moving the mast back makes it easier with weight transfer.
How much are you chopping the 220 stab using the 1040? I've only tried the 280 and would be interested to know if there is a lot of difference with glide and stability with the 220.
