I played with Iontec a few months ago with a Eagnas Synthetic gut(perfect spin) and didn't realized the pocketing I was feeling is due to Iontec. I gave credit to perfect spin at the time. However, I tried Perfect spin a few other times with full bed, hybrid with others and just can not get that same pocketing feel back. I strung up NRG2 yesterday at 58 main and Iontec 54lbs cross. I played with it for about 3hours tonight and it's just a great set up. Every shot I feel the ball pocketing the racquet like no others. I am going to get a reel of this string. I am thinking it almost doesn't matter what other Multi I put on main as long as Iontec as the cross. I need to string it at main either full bed or hybrid to see if it gets any better.
