Why'd you go so big when buying the Hero?

I'm a big fat fuck, but I rode my buddies little 152 Sims board, and it was quite fun haha. Definitely a different expereince being on such a small board and weighing 220, but oh well. Whats the width of that Blunt at the waist? I wear an LG/11, need to make sure my feet are going to fit.
