Cargo,

Most excellent...and thanx for the compliment.

I personally don' t take much stock in paper tuning..mostly because I suck, and my form is not that consistent. So I know that I' m not always going to get consistent results from paper.

Group tuning I used to do more of when I had more time to fiddle and shoot, IMO it' s the best way to fine tune a bow.

Lately, the thing I like to do is simply find absolute centershot, set the rest, leave it alone and play with arrowspine (different arrows, point weights, fletchings, etc) till I find a shaft that gives me the tightest groups at 30 plus. Most folks don' t however have dozens of different arrow shafts laying around, so they need to tune the bow to the arrow, I prefer the opposite.
