Racquet: Dunlop Aerogel 4D 500 Tour String: Victory Racquet Sports Acelon Supplemax String Gauge: 17 Tension: 55 lb NTRP Level: 3.5 Time Length: 2 hours Usual strings - Wilson NXT 16 Impression: Upon the first hit, these strings were similar to the Synthetic TCF that I played with in that they are both plush and comfortable. Where the Synthetic TCF felt "pillow-like", these strings felt like butter. If you are looking for a soft and extremely comfortable multi, look no further than this one. As mentioned in my previous Acelon string review, these strings worked perfectly for my spin-game. Slicing with my one-hand backhand was a breeze and I got a good amount of topspin on my forehand as well. While these strings don't grip the ball as much as polyester strings, you still get a good amount of spin compared to other synthetic and multi strings I have tried in the past. Like the Synthetic TCF, these strings are powerful so you might have to adjust your swing style and speed if you come from more control-oriented and low-powered strings. This can be changed as well by going to 16 gauge, higher string tension, etc. This is only my second time playing with a 17 gauge string and I really like it. I am not a string-breaker so this gauge was recommended to me and I didn't find any signs of breakage after my match. Loved these strings!
