If I may chuck my six eggs in-I've tried most of the above except placing arrows across the limb bases to check for riser twist. I would still check using two arrows across limb tips aswell though just to be sure the whole length is ok.
I tried using a straight edge alongside my Matrix sight window and various places but was not convinced it was a reliable reference point. I resorted to using a laser fixed to the sight block fixing holes which allowed me to swing an arc 360 degs and check everything in one go including the longrod. However I then considered that even the sight mounting surface might not necessarily be entirely flat and in line.
I did have a misalignment on a longrod on one setup, but rather than mess about with the bushing and being satisfied with the rest of the setup I modified an old allie V bar. I only filed a thou or so off one side and after a few attempts the longrod came into line.Just got to remember to fit the V bar the right way round!
All I know is my groups got a bit tighter afterwards.Thanks for the above article,really informative.
