I just worked on a Shop Fox dual drum sander for a customer, and it had hook and loop sand paper on both drums. The hook side was attached to the drum by Some type of double sided tape. I would think self stick material would have been better than the double sided tape. I don't know how well it actually works, but my customer said he hasn't had any issues with the paper being a problam...being spongy shouldn't be a problem either, you have to remember it's a sander not a planer.
