Those pads do sound great on the video but they are pricey! Figure around $200 for a 4 piece set.
Do you find their rebound to be very close to drum heads? They look like they'd sound and feel pretty authentic, perhaps a tad too loud for my residential setting. Especially the snare and bass drum. I still use Remo Silent Stroke Heads to practice quietly.
BTW, Larry Levine's hand and stick techniques sound amazing. His gripping on the sticks, speed and finesse remind me of my drum teacher's skills I used to hear when he was demonstrating exercises at high speeds from Stick Control and the like, on the old school gum rubber practice pad. Speed and smoothness combined for quite a sound on just a rubber pad. Why can't I get that sound?
