Thanks for the tip off about measurement of board, I do think you're right, and my shorter legs/longer torso ratio should actually be an advantage at least in terms of getting my legs out of the water on a speed run. In retrospect, I think the "too big" thing w/ my antique Mike Stewart was width mostly. Making someing around 38 or 39 X 19 likely a lot more manageable.
Noticed last night looking at side by side photos of your board and the Tuna tail by tail, Tuna has flat/parallel outside the concave and yours are actually V-panel chines or whatever the term would be. Should make your board a lot more responsive and easier to turn (with small sacrifice in drive)(always trade-offs).
