No question weight is more important than height, but height matters to the extent that it relates to your stance width. For instance I have a 157 Proto HD, and with my stance I'm on the outermost boltholes. I couldn't ride a 154 because of my height (although I'd be too heavy for it as well)
I know you think you thought you knew what you thought I said,
but I'm not sure you understood what you thought I meant.
