So this reply is going to two different issues I posted on this page. The whisker biscuit fiasco, and the proper spine issue. So I took the advice from all of you guys and have made a few changes and I am very pleased with the results. I got rid of the whisker biscuit and got the Hoyt QAD. I changed out my 400's and went to the 340's. I added one more change and added helical vanes. Ran it through the chronograph, lost 10 FPS. Everything was going fine at normal distances, I noticed that I never had the occasional flyer that made you sit and wonder what the heck caused it. I had to make a pin adjustment at 60, and 70. But at 70 my shot group was literally cut in half from before! Just to make sure I wasn't just getting lucky I did it a few more times. I shot a six inch group with 5 arrows 3 times. I am very pleased. Yea I lost 10 fps, but I feel more confident that I won't have any unexpected flyers anymore which is good to me!
