I have been experimenting with lower tensions using synthetic guts and multi-filaments. The overall stringbed hits fine, but the movement in the mains quickly introduces more variability and reduces the amount of control. Movement in crosses is not so much an issue due to notching of the mains which "locks in" the crosses. What would be the best way to reduce movement in the mains? 1) Increase the relative tension in the mains? 2) or increase the relative tension in the crosses? I have seen stringers argue it either way. Would it make any difference, and what would be your reasoning? Also, are there any other simple suggestions (Jet method maybe? I don't really want to mess with poly strings or stringsavers), and what would be your rationale?
