It's give and take,
The give, is a bow w/ a lot of pre-load in their design. It will feel silky smooth and launch a very quick arrow.
The take, is they can be sensitive to shooting flaws such as inconsistent finger pressure on the string, incorrect pressure on the grip, ect.
I was told by a respect bowyer that if you take a recurve ''unstrung'' and lay it on a flat surface so the limb tips touch 1st. The further forward the limb tips are in relation to the bow's riser. The more pre-load that bow has in the design.
