if u get the quadropad from steve weiss it comes w/ the laminates.

and i personally think u should have them on.

Well, Heres what I'm Coming up with, not an exact awnser, but it helps.

1) The HH slimpad says for the feel of a marching snare drum, a thin layer of gum rubber, While the stock pad says for the feel of a tenor or bass drum, I'm assuming that means Multi-tenor too.

2) I use a slimpad without the laminates for rudiment practice, I also have a set of my schools tenors I use for practice, just from trying to tell with my hands, There does not seem to be too big of a diffrence, the pad might be a little higher tension.

I would go to risk that the pads on the quadropad are probably a little thicker then the slimpad, but thinner then the stockpad. Of course, I've never seen the quadropad in real life, So I can't exactly be sure.

i think you should look into a different pad. the quadropad is really weird. i tried it and i didn't like it. i prefer the promark tenor pads. here's a link
