Trying a new board

Hi everyone,
So lately I've been demoing the Channel Islands average joe 5'7'' 36L. I really enjoy the board,but recently I've been wanting somthing a little less bulky. I've been looking at the rocket9 which is only has 30L. I was wondering how different the boards would be in preformance and takeoff before I demo the rocket 9. Any insight would be appreciated!
