Comments: I am using this as a cross string paired with Lux 4G 1.3 mains on a Steam 105S at 54 lbs. The biggest
benefit is that it reduces notching (only string I've found to do that). I guess it provides a nice wide base for the mains to slide on, so
this combo has very good spin. It's tension maintenance is nowhere near the 4G though, and I notice about a 12 lb drop off before
the XS breaks. Full 4G only had about a 4 lb drop off. Odd that the cross would break first, but it has been consistent in that regard.
I only got about 5-7 hours out of Prince Duraflex as the crosses, and this gives me 15-20 hours.
