Cube - Set

Cube is an intriguing string - a string of very deliberate choice for its peak properties. Not right for everyone, as it's quite firm (yet not uncomfortable, especially when crossed with a softer cross). It's not Grapplesnake's most well rounded string (that's M8 for me). But if you love spin and take massive swings and you want to accentuate that with an aggressive shape and a deader feel (i.e., low powered), this is a wonderful choice. Given its shape, I was concerned about inconsistent launch angle but I didn't experience that at all (I crossed with the very soft Luxilon Element IR Soft). Comparable to Weiss Cannon's Ultra Cable for sure, but so far I think its tension maintenance is better. Great choice for 18x20 string patterns where you need extra help to get ball shape.

USTA competitive 4.0 all court player, Head Speed MP 52lbs. I gave these a try on a whim and they became my favorite strings for Mains, on the crosses I use the company's Irundanji strings and the duo creates a spin friendly, arm friendly player racquet.

Trying to decide if I’m going to switch to Cube. Might even be spinnier than Ultra Cable

Previously was using Weiss Ultra Cable. Cube has same type of easy spin generation but a plusher more comfortable feel. I would say there is a bit less power, but stringing 2-3 lbs less as recommended helps in that area.

Using in a Head 360 Extreme. This racket provides easy access to spin and a good pop on the ball with high trajectory. To control the modern racket, extra spin is helpful. The problem with many poly strings is they are stiff and although give good control are tough on the arm. Cube seems to address this well with its strong spin generation ability but plush softer feel.

I tried Grapplesnake's Cube string for the first time and was really impressed. While stringing my Wilson Roger Federer with the Cube, I was concerned that the performance of the string would be harsh and unforgiving judging by how little the string flexes when tensioned. In this regard I was very surprised as the string has the exact opposite characteristics, it gives a plush feeling and is very responsive and dynamic; there was no harshness or stiffness to the string at all! That said, the Cube has a stern personality, and is unforgiving if your strokes are squirrely or hesitant. The string bites the ball very aggressively and therefore rewards the player for good racquet-head speed, topspin and early contact. On the flip side, the Cube is not very accommodating to late contact, abbreviated swings or clubbing (reactive) groundstrokes . While this string delivers a nice well-rounded combination of controlled power and uncommon grip, its qualities reveal themselves best when you swing with clear intent and good timing. Where some strings can compensate for your lethargy, the Cube doesn't have a lot of sympathy and definitely lets you know when you're slacking.
