If you have access to an arrow cutter or live near to a friendly archery shop like custom built in Guisborough then get your arrows an inch or so longer than you normally would (so they are just on the clicker plate). If they are a little weak then cut them down by increments of a quarter inch untill the bare shaft tunes with the fletched arrows. ( I find that a half inch can make quite a difference to the tune). if they are a little stiff then go up a weight in pile and repeat the process. I also tune using pile weight and using a combination of these two methods I can get a bare shaft touching the others at 20yards. I have two sets of competition arrows, Ace 570's with 90 grain piles and Ace 520's that are half an inch longer and have 110 grain piles. The tune is almost the same (sight marks will vary of course) I got the 570's a couple of weeks ago and have already shot a 590 Portsmouth with them in the postal league. I shot a 578 FITA 25 at Pendle with the 520's so the system seems to work for me.
