What you have done can be done dynamicaly (shooting) or by using a spine checker which is done statically. When purchasing new shafts, all should be tuned together and shot bare shaft.
One extra thing you could do once all are grouped is to change the nocks! You might find this equally interesting...this too takes about 1.5 hours and does your head in. But then the benefits are huge...like getting GMB and shooting for G.B.

Well done, very few outside of the top G.B. Elite are aware of the issues concerning arrows/shafts and the importance of nock tuning...give yourself a very big pat on the back.

i diidt know this till i did the personal course at lilleshall in oct last i will be doing this before the outdoors season with my arrows
