If the board is that nice, how about posting a pick? A 6 footer should be enough, it's a little easier to retrieve your board. If your'e surfing grindy waves you can get one that's extra thick. I'd stay away from comp leashes as they are more prone to break and snap back at you.

if you using flippers i find a 8ft comfy, if no flippers a 6ft is great. maybe its just me, but if i use a 6ft with flippers it means tangle time for me...
