RE: mechinacials. dont think i ever use em...
Yep maybe, I take the time to tune the bow to shoot, four bladed muzzy, and steelforce arrow heads. Those are what I used to qualify my tunning. I get all to group with the filedtips.
Like you I have not yet found a shockwave defective out of the box. I take them out and take the rubber off and tip them up. the blades should fall open immediately. If they don't check for a burr or bend blade. I never had any that didn't pass yet.. then I check sharpness which is usually good. then put the rubber back on and spin it on the shaft. Ready to go then..
By the way what is the straightness on a CXl 250 arrow??
