Thank you for your quick response and suggestions, as always they are most insightful. I knew I was forgetting to mention some aspect of my setup. I use the stock fin, I believe it is a Drake 58cm, though I may be mistaken on the length. I sail in open ocean, no weeds, so I could easily switch to a larger fin. I figure try new rig+new fin before going for the new board? Or do you think that, even with the 70 cm fin, not much will happen unless I upgrade the board? I appreciate your help again. Take care.
