The Limbsaver does feel more squishy, however that doesn't mean that it absorbs more recoil. I have a kickeez on my 12 ga o/u and it performs extremely well! Hollow spots simply mean less material to absorb the recoil. Limbsaver pads do work well, and I like the slip on recoil pads they make for the sake of convenience, but if you aren't looking for a slip on, kickeez is the best from my experience.
