One aspect with a linear control rubber if you are facing a strong incoming loop and you keep grip relaxed and do a compact low power stroke, that almost looks lazy, but you are doing a defensive topspin that is so reliable under pressure.
That is one of the things I liked with Karis, when under pressure with topspin, I could get the ball back. Wasn't overwhelming, but better than pissing away the point straight away. Similar thing with counter-topspins - if I kept grip lighter and did the counter, I wasn't blazing it, but I handled the spin, made my own, wasn't real powerful, but I still made an attacking response with high percentage. That ended up counting for a lot.
Satisfying in that you glue on a sheet, you can keep it there forever until it almost falls off. I got way more hours out of Karis than MX-P, like double or more.
