No it doesnt change anything just noise and bow just i dont know like you forgot to shoot is the best i can describe it.It is like the string just stopps I really think I STOPPED ANY deer jumping the string I had smeone else shoot my bow today and I listened I just shook my head I own long bows and recurves and never heard less noise from a bow.How is that x force I would love to shoot one but there isnt any one within 200 miles of here that carries them I dont want to buy one without shooting one.You think the indians are going to sue fred bear for copying there bow idea oh then the cave men are going to have to sue the indians this could get ugly
