I'm looking for my 1st cat; I've looked at a used 16, but the hulls were shot. I've found a nice H14 Turbo, but I'm not sure if I need a 16 or not. Can anyone tell me the difference between the two, other than the obvious 2'? Is it a speed thing? Does it have anything to do with my weight? I'm 190, the girlfriend is 135. Thanks
