I've got a BT48 PRSAlpha Buddy with an 8' powerstick. I haven't found a spoilboard support surface that I'm pleased with so far. I've tried 3/4" MDF, 1" MDF with some material removed for weight considerations, and I've also tried laminating together two layers of 1/2" ply. In all cases, I've had issues with my board bowing. Resurfacing doesn't help as much as I'd like, as the board bows up off of the support wheels below it, and flexes as the cutter presses into it.

Honeycomb aluminum seems like it would work really well, but I've never worked with the stuff. How difficult would it be to mount it to the powerstick? Has anyone tried using that material?
