I've searched and found a few conflicting answers. Suppose I'd like 60 lbs. What do I use for tension in the mains & crosses if I'm using: 1. 16g poly mains, 16g syn gut crosses 2. 17g poly mains, 16g syn gut crosses 3. 17g poly mains, 17g syn gut crosses 3. 16g syn gut mains, 17g syn gut crosses And is there anything to know for the newer "multi" strings when using those with a cheaper (syn gut) cross string?
