Absolute Rating Durability Power Control Feel Comfort Spin Tension Stability
Strung on a drop weight machine in two pieces. Played for approx. 2 hours indoors.
The string seems wire-like and tends to kink during stringing. Playing characteristics are solid at best, feel is rather dull and sluggish. Unfortunately not recommendable!

Easy to string, was a bit slippery so easy to do crosses. Asides from that I didn't care too much for this string. It didn't have that power people rave about. I wanted to like this string as I heard good things plus it's well priced. But I didn't like the feel of it too much, was kind of mushy. It was definitely soft but I couldn't get the spin from it. It didn't have that awesome bite you get from a lot of today's newer offerings. Nowhere near as good as Luxilon, I almost feel this string is outdated.

Compared to the Alu Power this string didn't do it for me, not as much power nor spin and didn't have that wow factor. It seems pretty generic.

Strung in two pieces.
Played outdoors at warm conditions.
I had played it some time ago and was very happy back then, this time it was the same. The Energy does everything well, does not stand out in any department, and comes at a very nice price for the performance.
I think it is not suitable for hard hitters, but recommendable for players looking for a soft and touchy string.

Comparison relates to Signum Pro Hyperion. Haven't played the Hyperion for some time now, but if I recall correctly, these strings are quite similar.

Easy to string.
Played outdoors on clay with Head ATP and Wilson Tour Clay balls.
The Energy is much better than the Polystar Classic. It plays comfortable yet crisper than the Classic, but does not reach up to other non-textured top of the shelf polys. Interestingly, spin is better compared to the Polystar Turbo which I tested before. Somehow the Energy grabs the ball better and provides good feedback on impact. Balls scatter a lot less than with the Classic and I had better precision in my shots. Tension was maintained very well over the 4 hours of play.
Solid middle class string.

I was really happy with this string!
Strung in two pieces. Played outdoors on clay in hot conditions. The Energy lasted 4 hours so far, and within that period I can say:
1. it is affordable
2. it provides good power, comfort, control and spin
3. touch is excellent
4. it won't last much longer than 4 hours
If you like that kind of package, the Energy will be great for you.

Yonex Poly Tour Pro 125

The Yonex is a great string, but I could not really make friends with it since it provides too much power.
The Energy is more balanced overall.
