I think a lot of this might be stance and ability, but something I've noticed the last couple of days is when I go down a foil size (Naish 1440 from 1800), when I'm powering up (gust coming through) then the nose seems to dip. I noticed this the other day when I went down from a 6m to 5m wing, without changing anything else, I felt more balanced. Yesterday I was out on the 1800ha for a couple of hours on a 5m and felt pretty balanced. Today on the 1440ha with 5m in similar gusty conditions, when ever the wind picked up, I felt the nose dive (had to load up back leg) each time I sheeted in / went to go faster. Is there something about stance / position that means when you power up, the nose of the board wants to dip?
