sorry for the late review, but i was just able to get out there and hit after a short layoff.
39 year old 4.0 all court player currently using a Dunlop Aerogel 500 Tour 4D
i used to use much more of a "players frame" with a tighter string pattern (18X20) with higher string tension, but due to having some arm problems, have recently switched to more of a "tweener" style racquet with a more open string pattern and added some weight to it and have really backed off on the tension. i have also been using multifilamint syn in an effort to save the arm and would try out some new guts if they weren't so expensive
i hit a heavy ball and am a frequent string breaker.
i used to hit BHBR 17G and really liked it, but do to the previously mentioned arm issue, i have gotten away from polys.
i thought that this string was going to be very similar to BHBR, and it was, except not as good. i found it to be very difficult to string, even more so than most of your hard coiled polys.
Tension it is strung (please note if strung as hybrid or full set)
55 lbs, hybrid used in the mains / with alpha gut 2000 in the crosses.
Your regular string set up
still experimenting with different strings, but one of my favorites is BHBR 17, or Dunlop Black Widow in the mains, alpha gut 2000, or any other similarly softer string on crosses, 55 lbs.
Racquet brand and model string is installed in
Dunlop Aerogel 500 Tour 4D
Power (or lack there of)
you definitely have to take your cuts at the ball and you're not going to get any help from these strings, which i thought felt a bit dead. okay, i guess, for a baseliner that takes big rips at the ball. you don't get as much "bite" as i thought you would from a twisted poly.
Feel
what feel??? i felt that these strings were a bit dead and even though i strung them on the low side, still felt like i was using a paddle.
Tension maintenance (how long it holds its tension)
i have not noticed a significant loss of tension after about 10 hours of play over about a week and a half.
Overall comments and feedback
not the worst strings i've ever played with, but i would pay any significant amount of money for them, as there are other similar types of strings out there that are comparable, but better performers.
