Personally, I don't think the Slimpad feels all that accurate (unless your drum feels like playing on wood). I prefer my old RealFeel.
It was starting to seem like I was the only percussionist to think that way. lol
I've had my original RealFeel for nearly two decades now. I wouldn't trade it for anything.
