I ordered a set of Tradtech Black max carbon wood limbs. $219 at Lancaster. Wanted a cheap set of limbs to play with. I ordered 55 lbs. Thinking that on a 19 riser that I would lose 2 lb. And I typically lose 10 lb for my short draw length. That has been correct with 6 other sets of limbs. So I was thinking 43 lbs end result. Playing with the idea of a slow arrow. A point on at my average yard. LOL, but after installing, they pulled 56 lbs. Mercy, I checked them at 28 inch draw and it was 67 lbs. LOL, they missed it a little bit. Am I assuming wrong that the weights given are for a 17 inch riser? Will they take them back?
