The Iontec salmon is a little stiffer than the Silverstring but still very comfortable in the 99S. Both were strung at 56 lbs on a lockout machine. I actually prefer the Iontec because it is stiffer. The Silverstring became too springy after a couple hours of play. The Iontec has stayed firm and solid so far through roughly 4 hours of play. Both strings provide great feel (for polys anyway) and spin potential.
I've got Iontec Hexa 1.25 strung up now and am hoping the weather is nice tomorrow so I can test it out.
