Is broadhead tuning the final answer? That is if you get broadheads and field points grouping together at multiple yardages, then that means the bow is tuned and nothing else really matters, right.
You are exactly right about making sure your bh's spin perfectly. Any wobble at all and they won't tune properly. I will say that once my centershot is set by walkback tuning I don't move the rest. If the bh's continue to impact left or right of fp after walk back tuning then there is an arrow spine problem.http://www.archerytalk.com/vb/showthread.php?t=918146 post # 7 from this link.

Broadhead tuning question for you all
--------------------------------------------------------------------------------
When you do this are you suspose to shoot a field tip then a broadhead and just keep rotating every other shot and move your rest and sights accordingly?
I'm sighted in with field tips out to 50 yds but when I screw in a Broadhead (Wasp SST Hammer 100 grain)they shoot high (about 2") and right (about 3") from 40-50 yds.

Adjust rest/nocking point
--------------------------------------------------------------------------------
If broadheads are shooting right of field points, move rest ever so slightly to the left. If they are shooting high of field points, move rest down (or nocking point up) again ever so slightly. Repeat until you get the broadheads hitting in the same spot as the fps. Always move front (point end) of shaft towards where the field point is hitting. This is only done after it is determined that there are no problems causing the broadhead tipped shafts to impact differently than the field points such as vane contact, misaligned broadheads, etc., etc. I don't even bother to try to tune a broadhead tipped arrow if the broadhead does not spin perfectly without any wobble. Of course if there are any experts out there please feel to jump in and correct me if I am wrong about this. I also believe shooting a broadhead tipped arrow is a good way to fine tune your bow. Shoot the perfectly aligned broadhead tipped arrow (matching bh and fp weights of course) and use the above methods to fine tune your rest position based on where the broadhead tipped arrow hits in comparison to the field point tipped arrow.

Now throw on some 125gr BH's and see if the gap closes even more.Does this make sense to anyone? Also, now my bow is maxxed out and I can't close that 1" variance any further. Is 1 - 1.5" close enough do you think?
I'd get 340's. I'm shooting a 30.5" arrow at 60lbs with 100gr heads out of my Commander, and I'm pretty close to the line between 340's and 300's. That's with 32" draw. I would try yours at 30" with your 30" draw, then cut them down if you need to stiffen them up a bit.Looking for the shaft size here.
