I have the Lami-Cell pad and I love it, but I use it for a saddle that is too wide and tends to sit too low on the withers. It might be a little too thick and stiff/structured for you if your saddle already fits well. Something like a ThinLine or gel pad would probably work better for you.

Okay like I said earlier.. maybe I don't understand the mechanics behind a thinline pad, but how can a piece of deli meat absorb shock and cushion.. I'm pretty sure if I were to put that thing on my back and you sat on me, I'd still feel your bony butt in my back the same as if I didn't have one on... I know a saddle goes on top of it when on a horse, but I just don't see how it does anything but take my money.
I don't really know what makes this pad different than others but I can say I see a difference in my horse using the thinline pad.
