Absolutely correct, my recurve has no trouble with 15 pound spine variances. The sighting difference between my longbows and center shot recurves causes trouble for me, but it is all what one gets used in a way and the style of shooting that works best for the individual. With Hill style shooting and Hill style bows it seems like the arrow likes to have something to fly around.
Dick Robertson said the same thing concerning his longbows. Perhaps that is why the recovery rate and forgiveness of a good wood arrow works so nice in a longbow.
