If your arrow is shorther or the same as your 28.5 DL you may be ok with those arrows. You can add a wrap to your arrows to stiffen them up.

It sounds like your tuning is getting close and you do need to adjust a little to the right. You also need to restup a littlea little or your nock down a little. 1/32" max.

If you go with Gold Tip get the 5575's and you will have good spine. If you stick with the Redhead arrows go to a 6075 shaft and you will be good too. A little stiffer spine is always recommended for hunting.
