Full set or hybrid:
I set this up as a full set
Tension used for playtest:
50# on a Gamma Progression FC .
Regular string set up:
Multi mains and poly crosses.
Racquet brand and model used for test:
Volkl C10 Pro Tour.
Power of test string:
I would consider this a mid powered poly string. I had lots of control and power hitting a rare out. Mostly I've painted the lines with this string with good speed on the ball.
Feel with a poly is something to found very rare. I'd say the feel of this string is a medium type feel with ok touch on the volleys.
Spin with this string was great, since my regular setup is multi mains and poly crosses this 4G had a little more spin then my reg setup. A lot of balls my opponent let go because he thought they would go out but at the last second they would drop right in.
Not the most comfortable string out there, but for a poly it is ok. I was feeling a tinge in my elbow, but maybe it was because I didn't play full poly in a while.
After 2 hours of singles they are a little notched but not too much. I haven't popped a poly string in a long long time. So far this has a lot of life left.
Tension maintenance (how long before it became too loose or unplayable):
So far it has been very good. But more time will tell.
Control (predictable trajectory? performance on different strokes and swing speeds?):
Control is one of my favorites pros for this string. I was able to put a lot of spin and power on the ball and it would still land in. I had amazing serves down the T and out wide most of them landing in. Incredible angles were something else, just wow.
Compare to the string you use most often:
It's like comparing apples to oranges but I will try to compare. Of course my multi/poly hybrid pops much faster than the full 4G and it is much softer than 4G. But 4G has a lot more spin and control compared to my regular setup.
Tension recommendations (after hitting it, would you recommend a different tension? Why?):
I'd lower the tension to like 40's where I never tried a string that low of tension just to get the comfort up a little.
Summary: List 1 or 2 primary likes and dislikes.:
I liked the control and spin that I got with this 4G and the free T-Shirt of course
What I didn't like is the comfort but hey this is a poly and I was expecting that for sure.
Thanks TW for the playtest.
