I use NRG2 18g in the crosses with Pro Supex Big Ace Micro (19g) in the mains and it provides me with a silky smooth blend of power, control and playability I haven't been able to replicate with any other multi - including Biphase. Compared to Biphase, NRG2 feels more plush and doesn't require the break-in period the former requires. It's silky smooth from your first stroke and when it settles in, it's so nice. Durability for my setup, despite the thin gauge, is pretty impressive in my POG 100's with a 16x19 pattern. Love this stuff.
This is the best string for feel and spin that I have ever played with. Very responsive and with a 16X18 string-patterned racquet, it gets great bite. For an 18 guage string it has very good durability.
For the price, this is the best multi-filament string on the planet. Great feel and durability is better than expected.
I give it 8 out of 10. Tested 17g. Playability 9, power 7, comfort 6, durability 10, topspin 7. Good strings however behave way better at tension under 56 lbs (would recommend 48-52 lbs)
Lasts at least 4 rounds of 2 hour play. Feel is excellent. Super comfort. Not overpowering. Dumped poly due to shoulder pain, but even without the shoulder issues I would have made the switch back to a multifilament, and this is at the top of what I've tried. Tried the 17g and 18g, 18g wins for spin. Groundstrokes are pinpoint, volleys are solid. I'm a big hitter, with lots of topspin.
I use this string exclusively. Great feel, spin, and control. I definitely recommend this string to anyone looking to upgrade from a standard synthetic or something like a Wilson Sensation.
