Someone was posting on here about wheel well boards and how they pair with ventures, can't find the original post so I'll just post here instead.
I'm skating 5.6 ventures, white thunder bottoms, bones soft tops with flat washers (odd config I know) with some probably 52/53mm wheels on an 8.5 polar with wells. Had the first skate on it yesterday and the wells definitely help out with wheelbite a fair bit, I was getting away with some shitty landings that'd normally throw me off, carving seems somewhat better too.
Looking at the marks on the underside, it's still been biting a little bit on the outskirts of where the wells actually are. Could be that the wells are designed for trucks with a smaller wb, or the fact i'm running trucks slightly shorter than the board. Overall though I'm very pleased with it.
