After searching for a while on this site for tuning tips I decided to shorten my draw length and see if it helped my consistency (bad groups, bad torque). So far, it looks like I made a good decision. My question is whether or not I should shorten my arrows? How should you measure your arrow length to make sure you get enough clearance for fixed blade broadheads?
Right now, they are 31" from the groove in the nock to the tip. My draw length is now 29.5" (I think), are my arrows too long? My set-up is not perfectly tuned yet but it is much closer (thanks to more info from this site) I just don' t know what effect shortening the arrow will have on my tuning, will it improve bare shafts tests? Right now, bare shafts still hits slightly low (1" ) and left (1-2" average). I had to really move things around to get this and a decent paper tear (way out of center, nock low) but it tests-out much better?!?
I will have to take them it to be cut, I don' t have the equipment to do it at home.
Thanks for any help.
PSE Nova Extreme - 66# draw
Cabelas Stalker Extreme Arrows 65/80 (8.7 gpi, 100 grain point, 4" vanes, 4 dgr offset, don' t know total weight?)
Scott release, limb savers, peep sight, string loop, whisker biscuit

It looks to me by your information you have most your information right in front of you. You know your grains per inch, you know your arrow' s length, you know you tip weight. Most 4" vanes average around 7.7gp vane. So you got a real good idea of your weight. You say your hitting low & to the left. What about paper tears now after your adjustments? What about your Forward of Center on your arrows. Cutting your arrows back another inch or so, depending on your rest style can have effects on FOC, and Spine. Both can have effects on paper tears low & to right or left. www.eastonarchery.com go to the Tech Room for eastons tuning guide. This will help answer your questions.
