Spring , You can probably shorten your arrows allso and get them to spine stiffer . Seems to me you are shooting a long arrow for your draw .

Backed down the weight to 63 and adjusted the spring tension. Arrow flight looks great and am getting 3" groups @ 40 yards and stacking them inside that range....quite happy with that.

I thank you all for your input...also, a side note. I had one arrow pretty much implode around the fletchings while I was at full-draw. Talk about a scary moment...was the first time I had ever had such a thing happen. Luckily nothing was damaged...restrung the bow and all was fine.

Anyone else ever had a GT do that for no apparent reason?
