The bows probably 7 or 8 years old but in like new condition, its a Martin Cougar speed flight. I shot it over a chrony & was getting about 235 fps out of it if that helps.

I'll try paper tuning but I believe the knocks are ok, I went thru alot to get them right while fletching. It looks like the fletch is hitting the rest between the prongs where they pivot, I wanna call it the barrel but dont know if I'm correct. I'm fairly sure the contact isnt on the riser & I shoot tight groups out to 25 yards, at 30 they open up to 4 " or so but I think its me as I dont practice much beyond 20 - 25 yards.

Thanx for the suggestion.

Just looked at a size chart for easton aluminum shafts & your right, I'm right on the edge & might be underspined a bit. I been shooting Gamegetters & 2219 is the next size up, but then I'd be overspined. Whats better?
