Thanks for your input! I was sailing a couple of days ago with my Hypersonic 125 with 8.5 in subplaning condition for other sailors, but with my usual pumping galore, I have managed to plane quite often. I have to suffer again from joint pain in my previously injured right elbow though! I'm so tempted to pump at smallest of gusts to maximize my planing. May be that's my problem! Thanks again for your suggestions.
