I have my sanity back! Nockset being way off was masking the stiffness of the arrow; if that makes sense??? Lesson well learned: forget what the tuning book said - if it is not getting better moving things in one direction - turn around! Things are not perfect but 400s with 200 grs. in front seem to be flying pretty good. With feathers, they fly like on a string. Bare shafts are hitting the same spot but slighty nock high. I put 300 grs. on the front of the 340 and they actually shoot well with feathers - bare shafts are still showing a stiff arrow. Having fun but mosquitos (La's state bird)drove me inside. Thanks everyone!
