I can address the manners of the limbs. this may be a little outside the context of the forum but maybe the moderates will let me answer the question.
I have put the limbs thru their paces on the 20yd indoor range. I used a 19" Bernardini Cobra and an AGF Safari sight. Barebow weight on the riser but no stabilizer. the Cobra riser is like a naval gun platform. it will shoot the limbs as good as you can shoot them.
The limbs have a great draw. the "clicker" area is best. i have not done a f/d curve on them i mostly go by feel. the curve feels very flat at the back of the draw. makes hitting you draw a bit easier. the static recurve give a feel of a much longer bow. the limbs are stable, extremely quiet, and quick.
groups are nock busting.
ok back to bow hunting....
listen we don't want to tout these limbs too much. right now they have the best price point vs performance, material, workmanship on the market. don't let Wingnut know
