As I recently joined the Prince 93P club, I await your review on 93P wtih high differential Kev/ZX set-up.Sorry My bad. Initially i felt like it was reg. Kev but its the same Kev+. I played with fully prestretched kev+/ZX @60/45 this time for 1 hour and still like it a lot without any major differences to 55/45, may be power was just tad less. Hopefully this time it will last longer than last time (14 hours). Anyways i just ordered 2 half sets of 16g regular Kevlar and 200' reel of ZX, and will try @60/45 once the current one breaks, i am sure it will last much longer.
