I have recently purchased for my 7'2" mini mal, the malibu full deck diamond-shaped pads from Squid and they seem fine to lie on (and surf on) but are slightly "spongy" so I roughed them up a bit, literally scratching them with a fork to try to make them sharper/rougher!!!

http://www.creatures.com.au/collections/traction/products/grip-sheet-black-510mm-x-510mm you can cut and stick as appropriate. I have added portions to my Cabrinha Trigger 2014 kitesurf surfboard in the spaces between their hex pads and on my shortboard where my back foot (just a 10cm wide strip ahead of existing deck pad) and front foot land. I placed some leftover Squid grip mainly where my chest presses against for paddling.
I have always obsessed about surfboard wax and constantly wax-combed it while waiting in the line-up...I genuinely feel full deck grips the go!
PS. I read the weight of these grips is a deterrent...interestingly the afternoon I removed all the wax from my mini mal and shortboard, each had enough crappy old surfboard wax, to match the weight and size of a cricket-ball!!! The pads are very light in reality and are being used for surfing by some like Jack Freestone...
