Trust me I'm a nerd about this shit haha look into it. Lib Tech's Skunk ape, the one with the skeleton graphic, you can't go wrong. I'd get like the 165W/169W. Not sure what size board you ride now but with the banana rocker you can size down, take 2-3cm off what you'd normally ride.
Get the skunk ape man. It's meant for bigger guys who need a freestyle/freeride machine. It's got the C2 also which will hold better at high speeds than the traditional banana. Check it out man. You're too big for the skate banana, but they make other boards with all the sick technology you want that will be better for you.
So I'm gonna get a sk8 banana but not sure if I should get the 156cm for the 156cm wide, I have 10.5 size boots but got toe drag real bad with my old board until I put on risers (waist width on my old board was 24.7). I DON'T want to put risers on my skate banana, will the 156cm cut it or should I just go for the wide?
Get the wide. You don't want to put risers on your sk8 banana and sacrifice some of the flex. I have a size 10.5 boot and I'm torn between the same two decisions myself because I used to get bad toe drag on my old board until I put risers on. If you're going to be doing lots of park then I'd especially say get the wide because you won't like riser pads in the park if you end up having to put them on...
