Richard,
I can’t give you a definitive answer on #3 but from my experience clear grip is not completely see through. If you check the bustin website and click on “the idea” link and then click on the year 2005… and then click on the number 3 on the left a pic will appear with some boards. The one in the middle seems to have “clear” grip tape on it, which actually is a bit milky.
Anyway, IP this contest is fire!
