lots does depend on the string build style - flemish will take more time to 'settle in' than endless, because of the flemish 'twist spring factor'.
a tight spun endless, using low stretch/creep dyneema, vectran or spectra, will only take a few shots to 'settle in' and then it's all about playing with brace height and nock point location.
with a 'one arm bandit' endless jig, spinning up a perfect string length with very little twists is far and away much easier than hitting the twisty flemish numbers.
in the weeks to follow, i'll detail the building of a simple 'unistrut' one arm endless jig and provide string spinning details ... hopefully a video, too.
