I have been messing with the process that Ryan Sanpai (sp) offered on the Push. I think it was Ryan.
Start with shafts you assume to be weak.
paper tune with fletch at a short distance. (then tune, trim length, add weight, cut weight, whatever is indicated) repeat until happy
shoot fletched shaft and a bare shaft at 10 yards (then tune, trim length, add weight, cut weight, whatever is indicated) repeat until happy
shoot fletched shafts, bare shaft, and a fletched broadhead shaft. (then tune, trim length, add weight, cut weight, whatever is indicated) until happy
move back and continue, move back and continue.
Sounds like a lot of time but I found it works.
One thing I do is set a minimum length and a desired tip weight before I start and if I cannot end up close to those desired items, I choose a different spine shaft and start over.
For example I like a 29" shaft with at least 145 up front.
I start with a 32" shaft and 190 tips and go to work. When shafts are getting close to the 29" length I start decreasing tip weight instead of trimming shaft. If I cannot get short enough or remove enough weight to the front, I start over with a stiffer spined set of shafts, or visa versa
