So many variables in WB from board length to the size of the skater, its almost a crap shoot till you find what is good for you. Although, all really good skaters can ride any shape or size board, most of the normal folk needs as much help as possible. I tried to be a vert skater for a bit and went up to 8.5" by 32.5" with a 15" wheelbase. It was stable on big vert ramps, but sucked on mini or even ramps up to 7'-8'. Even trying to street ollie for me made the nose hit the side of my leg. So I went back to an ATV 8.4" by 32" with a 14.5" WB. Its pretty much the best size for me at 6.0" tall. I feel a shorter board and wheel base might help with a higher Ollie, but I dont think it could handle a fast bowl over 6' deep. So i just balanced it out with what I ride now.
Interesting that ACE gives you a shorter wheelbase through truck design, as mentioned earlier. I'd like to investigate that a bit further.
