The more I play and the more situations I am in where I have to make a shot, even a routine shot, under pressure, the more "feel" has come into the equation.
I have been using Cyber Flash for over a year now and have gone through a reel. As a full string job, I have to say, it is about as numb feeling as they can get. Whether the string is new, a little used, or dead, the feedback is awful. A hybrid with PSGD or another crisp synthetic gut or multi can improve it, but its still not going to be great.
I had a Technifibre polyester in my current frame before switching over to my Cyber Flash and it was significantly better. I am gong to be be making the switch from Cyber Flash to a thinner gauge of something else. If I could justify the cost and the frequent res-stringing of Luxilon, I think I would still be using that.
With that said, I am playing in a tournament tomorrow night with a full string job of Cyber Flash.
