Multifinish is nothing near as 'grainy' as the decent gear of years ago. IMHO it's the fact that it's made so fine, to get over suction, that is what makes it slimey and horrible to use where there is less suction and in cooler weather.
Way unnecessary overkill mate. My 9mm boards were fine even when loading them up with S&C from a hod.
I've also never understood why people cut the corners off their boards, it's exactly where my hawk handle sits whilst ruling off.
