TW has this description for Klip Armour Pro:
"Unlike any gut you've used before, Klip's Armour Pro features a special coating. The white coating on Armour Pro provides a firmer response than one would expect from natural gut. Our playtesters have likened this string to playing with a poly/gut hybrid due to its excellent control, durability and ball pocketing qualities. Thanks to the coating, Armour Pro is the easiest natural gut we've strung. Players familiar with the feel of natural gut should string this string at 2-3lbs less than regular tension to get a similar power level."
I happen to like it, and think that it is maybe a little stiffer than Babolat or Pacific. It definitely is an exageration to say alone it plays like a poly/gut hybrid. But when strung tight, it gives reasonable control and spin. I like it best in a hybrid with BB Alu Rough.
