I have played previously with both Solinco Hyper-G and Tour Bite strings, and by far, I like this Solinco Confidential string the best. It provided me with a very approachable shots consistently where I could readjust my technique to correct the balls paths. I enjoyed over 20 total hours of playtesting until the string broke.
Tension(s) used for playtest: Solinco Confidential 1.25mm full set at 53/51 lbs (main/cross).
Regular string set up & tension: I have been using Ashaway Kevlar 16 main, 55 lbs and Prince Tour XC 15L cross, 53 lbs setup for over a year. Now, I am experimenting with 16/15L shaped poly main, ~53 lbs and 17/16 round poly cross, ~51 lbs. I have been using mostly Kirschbaum, Volkl, Weiss Cannon, and Tier One brand strings.
For the playtest review, I would like to make a comparisons based on one of my recent preferred string setup; Cyclone 15L main, 52 lbs and Kirschbaum Pro Line Evolution cross, 50 lbs.
Racquet used for test: Head Liquidmetal Mid (93 in2) 18 x 20.
Power/Control of test string: Playtest setup provided better accelerated balls using the continental grip, and the control was better as well. Solinco Confidential string provided more predictable shots based on my swing techniques. When my techniques were good, I generated awesome shots.
Feel (Stiff? Mushy? Muted? Crisp? Comfortable?): Playtest setup provided more muted and comfortable feel during the ball impacts at the net, baseline, and serves. I felt more ball pocketing with Confidential than my usual string setups.
Spin: The spin was there as needed and it was predictable! I could generate a much more spin than my preferred string setup when my technique was on.
Durability: The string durability was the above average when compared with the other poly strings that I have played with. Using the string savers or string lubricant is couple of ways to slow-down the notching if the additional durability is desired.
Playability Duration: Playtest setups provided a good playability even though there were many deep notches all over the main strings just before the main string broke. It was over 20 total hours of hard hitting.
Tension Recommendations: Playtest setups at 53 lbs main/51 lbs Cross were very comfortable for me. I may vary the tension within +/- 2 lbs based on the racquet head sizes. For the mid-size, between 53/51 and 51/49. For the oversize, between 55/53 and 53/51.
List any additional thoughts: Stringing the Solinco Confidential 1.25mm string was similar in difficulty as to stringing Kirschbaum’s Pro Line Evolution or Pro Line II. I did not have any trouble in stringing the Confidential.
The Solinco Confidential is a well balanced performance string that provided predictable controls and a above average playability durations. It is a definitely a must try string if you like the Solinco strings.
Would you use the included overgrip? Why/why not?: I really liked the feel and the tackiness of the Solinco overgrip. The overgrip performed well and the effectiveness is still present after over 20 hours of hard hitting tennis on the outdoor tennis courts. In addition, the overgrip length was just right. I used the double sided tape to take the plastic film off. I am considering to use it regularly if the cost is comparable with my present overgrip, Yonex Supergrap.
And lastly, special thank you to
@TW Staff and Solinco Company for the Solinco Confidential 1.25mm strings playtest opportunity and another very positive experience.
