Okay so i cut out BGU because of the tension loss and the fact that i have a match tomorrow. Strung at 57 full bed played in cold conditions. I've only played with this string one time but i love it! Better then BGU! Okay played on hard courts, i have a Vortex ES 100(wide string patten), i usually play with any full bed poly, im an advanced junior (in missouri valley they don't do NTRP for juniors) im a freshman whos number one varsity on the boys tennis team so i play usually seniors or juniors. Spin- ....better then Blue Gear Ultra. Really good, could get a lot of kick on spin serves. Controllable spin too. 9/10 Power- Seems limited, wish i would of strung it lower. I can't get enough drive-through on shots but it has good pop. I'd say...6/10 Control- Excellent. Could swing as hard as i can and it would still go in. 9/10 Feel- Hmmm better then BGU but not great. I think it needs to break in a little. Volleys seemed nice though. 7/10 Comfort- No problem here. I mean, it isn't like playing with gut but not bad. It's pretty stiff though. 8/10 Groundstrokes- Great, my favorite thing about these strings. 9.5/10 Serves- Very good, except for the limited power. Slice serves were good,kicks excellent, and i loved hitting flats with this. They would go hard and fast and when it bounced all the sudden it would just bounce into a different direction. (Due to technique and gear shape) I think i covered everything. Feel free to ask questions, my favorite string so far. I think i will be stringing up Signum Pro Poly Plasma 1.18 next, hope this helped! Highly reccomended string.
