As for your Thunderblast 16 suggestion for a hybrid cross, bravo! Been doing wonders for me with MSV Hex 1.23 in the mains at 52 pounds on my X-2 machine. I bought a set of the white (natural?) Thunderblast to do a side by side. I think I remember you saying that the white version was a good bit softer and that you preferred it to the black (not only because it doesn't stain the ball) Thanks again!
