I'm a fan of the Ashaway Zyex strings. They have great spin and feel but the negatives currently prevent it from being a regular string for me.
The original Dynamite had severe initial tension loss plus excessive string movement. You could string it up lower for the first session or you could string it up tighter for subsequent sessions - pick your poison.
With the current Dynamite and Dynamite Soft, the tension loss is better but somewhat still there. The string movement problem remains and the feel is improved. However, I managed to break a set in 2 hours...
Haven't tried the new Dynamite Tough set but will do so. Definitely will try the Zyex Monogut whenever TW gets around to carrying it. I think I used a set of the original Monogut way back but cannot for the life of me remember what it felt like.
