scotch

Hi all, my current pedal board doesn't use Velcro, but I'm looking at a nux bumblebee, and it dose. Is there much difference in Velcro? Is Hook and Loop different to Velcro? Warwick H&L, or 3M Velcro, or Scotch Velcro?? What are U guys (pro's) using?? Sorry to keep asking kooky questions, but...
