Here we go, now I'm gonna get it. Simple physics and geometry would say a longbow would be more forgiving. More length in the limbs means less movement at full draw versus a shorter recurve, less string angle too, and the string never contacts the working limb, resulting in a more forgiving, quieter shot. Picture if you will a 60 inch stick, grab it and wiggle it, now do the same with a 70inch stick takes more effort right. Little mistakes are forgiven more easily with a longer bow. Now, narrow, thicker limbs are sturdier than wide flat ones. If you don't believe me grab and unstrung recurve and give the limbs a twist they flex. Try the same with a narrow thick limbed bow such as a Hill...good luck. Recurves usually have a heavy riser and light limbs, longbows usually have heavier limbs and a smaller lighter riser this too equals more stability in the longbow. Again, grab a recurve give it a wiggle, grab a longbow and do the same, the heavier mass of the limbs is farther away from the center mass of the bow requiring more effort to wiggle than the light, wide recurve limbs with the heavy riser, where all the mass is in your hand just waiting for you to wiggle. The less variables you have at full draw the more accurate you will be. I still think it is absolutely your preference that will decide what you shoot. But this does make sense if you think about it. Ok, now let me have it.
