I play the Yonex Ezone DR 98 and have ordered some Isospeed Cream after reading about it's positive elements. I would like to know what those of you that play Cream string it at, compared to a standard poly? I assume I may need to string it a few pounds tighter than I am stringing a more traditional poly? Currently I have some Volkl V-Pro 18g in the frame at 46lbs. I'm a long time hybrid player, poly mains, synthetic crosses, but am trying all poly at this time. Suggestions?
