Velcro...my old nemesis.
Something I had a problem with in my early days was when I would go gigging. Inevitably my pedals would come loose from the board...not because the Velcro had failed, but because the *adhesive* had.
It's useful to note that even industrial strength Velcro has temperature limitations. Some have a failure point in the range of 110 degrees...
Sure, they won't be exposed to that most of the time. Unless...you put your board in a car on a summer day. Woof. Big ol mess.
I love me some dual locks but even with that stuff you have to select the correct adhesive backing. The Velcro website has all the information one needs to be able to determine what product # has what adhesive.
Food for thought. A solid mechanical solution that avoids adhesives all together is always going to be a great option.
