I probably gonna use Lux 4G 1.25 in mains at 55lbs and Klip Natty gut 1.35 in crosses at 60lbs. I liked this setup in my Ezones couple years back. It didn’t lasted long probably due to 16x19 pattern but I liked better feel and added power in comparison to full bed of Lux 4G. It should last longer in 18x20 and I can always restring crosses only once poly loses tension significantly. Stay tuned!Be interested to hear your results as I play gut/poly in mine exclusively. I tried poly/gut in my Gravity Pro and it was nice. Used Element in mains and VS in crosses.
