Rodb, not to worry, 25 oz is not too high, in fact for that size plane it's very good. If the wing load gets too low the plane will not tumble well, and will react too strongly to wind gusts. Contrary to popular opinion there is such a thing as too low a load, or we would all be flying powered gliders. Also the wing load gets higher as the plane gets larger, 28 - 32 are good numbers in the 90-inch range where as 18 -22 are good in the 45-inch range. Thrust to weight ratio, control surface size and deflection as well as CG location are far more important to high-alfa manuvers.
