If it were me (and I fully appreciate that everyone has different prefences), I'd be stringing ZX at soft co-poly tension (or maybe a fraction higher) if I was stringing ZX as a full bed. Ditto if I was stringing ZX as a cross with poly mains. ZX mains, soft multi crosses isn't something I have experience of!
Tomorrow I'll be stringing up ZX full bed in a Dunlop 200G XL (95 in, 16 x 1. I have been playing with BHB7 @ 42 lbs. So would you recommend going that soft? I had been thinking going mid-range, which would be 60 lbs.
