Since I have a new 160ish board now, I am wondering if I should buy a big i.e. 10 or 11 meter rig for it. I'm a heavy weight and prabably won't have trouble holding on, but this would be a rather large expense for me since it includes boom, mast and fin. Do they add that much more range to one's sailing range? I can go with a 9.6 on my current boom and mast adding to my 8.4.
