Don´t know about you but all the new strap/pad systems can be a bit complicated and incompatible between different board brands.
I have been using Mystic Straps on my boards for years, and love them, the best way to fix the screws through the straps is with the little rectangular rounded corner teethed metal plates (not sure the name), that look like these: http://www.nice-kites.com/NICE/T-Rex.html
These work much better than regular stainless washers in my opinion because they fix the strap, and are rectangular letting the strap bend at the attachment as it should.
Everyone used to stock them but i have not been able to find any today. I have been given the manufacturer contact in Thailand (Nice Bindings/PMT) but i think i would need to ship a bunch for them to be worth it and maybe it is a huge hassle all the way from Thailand.
I´d like to buy around 100 of these, to have sets for 25 pairs of straps.
