My Mojo came stock with 900's in the rear and even though I can surf all day ropeless I'm thinking about upgrading. I was considering upgrading to 1450's (Enzos) but I really don't like the idea of losing all that storage space under the seats. I'm seriously considering placing a couple hundred pounds of lead or steel weights in front of each stock bag. Would this take up any less space under the seats than the Enzos? I know I'd never get to 1450 on each side but it might be a good compromise. Also, do you think I'd notice 400#'s of lead when I'm ripping around or trailering? Never used the stuff so any advice is appreciated.
