I have a couple of boards with full deck traction that I use to kite surf. On occasion, I have surfed them and in the winter, in a fullsuit its fine. In the summer it will kill your chest, stomach and thighs. Even with a shirt on, the rash will get gnarly.
I think Julian Wilson may occasionally use a front foot traction pad. But I'm pretty sure you don't see it more often b/c of the rash that would ensue.
As a kitesurfer, I'm curious to know which boards you find work well for you for both surfing and kitesurfing - preferably good for light wind
There is a way to rough up the gloss with sandpaper that is surprisingly grippy. Not sure of the grit and you would need to be sure not to cut through to the hot coat but I have read that it is just as positive as wax. There was a product years ago in spray can that was great and it didnt rip you up even as much as wax would. Unfortunately its not made anymore. They do still sell peel and stick transparent traction that wont tear you up either, but it's expensive.
Xm surf more has a good clear grip sticker I put on all my boards and have used for at least 8 years. I wax on top of it. With anything like that you gotta trim it so that it doesn't touch your thighs though
