Review: Diadem Solstice Power 17G string

So I first found out about Diadem strings on my Instagram newsfeed. The first two things that stuck out to me after watching Diadem String’s exotic spaceship-technology like ads were 1] Teal Blue and 2] Star Core Technology.

Now if you didn’t already know, I am a sucker for loud colors. A couple of my favorites are Tiffany Blue, Mint Green, and Lime Green on Black. I guess you can say I have a thing for extravagant colors. Therefore when I saw the Diadem Strings Solstice Power in Teal Blue, I knew I had to try them out. And with outer-space futuristic “star-core” technology, how could I say no? Here are three key point regarding my experience with Diadem Solstice Power 17G:


Solstice Power grips the ball and allow for an immense amount of topspin, all thanks to its Star Core Technology. It really bites into the ball, providing extra grip and flick on every shot.

2] Star-Core technology wears out after ~10 hours

Solstice Power grips the ball extremely well, but only lasts a short while. When I play tested two packages of these strings, it lasted a combined total of roughly 10 hours. This is because the “Star-Core” texture wears out after extended play. So if you plan to use a full bed of Solstice Power, be prepared for the texture to eventually wear out. Just like when Super Mario picks up that Power Star, you have to take advantage of that Topspin power while you can!!

3] HIGHLY recommended to be used in a HYBRID SETUP

Solstice Power is best used in a Hybrid setup. This setup should include Diadem strings in the mains with the combination of a Synthetic Gut or a Softer Multifilament in the crosses. Hybrid Setups by nature provide more grip and topspin. In addition to that, the “Star-Core” texture will be better preserved because it is rubbing against a softer string. Now obviously a hybrid setup will not give you the same Spin experience as a full bed of Solstice Power, but it is a much more economical choice. Think of it like picking up a nice and controlled, extended-release Power Star, and not a crazy-buck-wild Power Star.

Conclusively, I would recommend trying Diadem’s Solstice Power if you are looking for strings that will give you that extra edge when it comes to spin potential. However, from a practical standpoint (if you don’t want to have to restring after 10 hours), I would strongly suggest using these in a hybrid setup. To utilize the advantages of Solstice Power in a full bed would require a lot of financial investment. It would mean getting your racket strung after every ~10 hours of playing, and at ~$15 a package, that can really add up. Even more so, $15 a package doesn’t take into account stringing fees.

I did a little bit more research and found out that Diadem carries softer, multifilament strings called “Impulse”. I would be pretty curious to see Diadem sell pre-packaged hybrid blends of Solstice Power and Impulse. Hybrid blends are often an overlooked option for many players, and the most popular one that I hear about all the time is Prince’s Pro-Blend with the Kevlar and Synthetic Gut.

But, if I were Diadem, I’d give it a shot. I’d put a cool spaceship looking picture on the front package with Impulse and Solstice Power strings, and call it Power Star with Hyper Spin Technology or something.

But in all seriousness, if Diadem is reading this, I just want to say that I would be more than happy to try that “Power Star” special blend. I strongly believe that people will love it. “Power Star” blend will sell out like hot cakes.
