Strangely enough I've just strung my racquet in the 68 version of their strings. I'll let you know what I think in the next week or two (only comparison I'll be able to make is against Ashaway MP though). I've heard great reports from a couple of other coaches though... Supposedly targetted Yonex NBG, but I've no experience of that string so far either!
Already tried it and it is a good string. Very repulsive with nice control but just like any string with nanotech,it has a sort of dead feel. It is also quite durable but it doesn't hold tension well.
