Yeah, the 18 is faster, but I think the 16 is better downwind...it is a bear to handle and wants to pitchpole all the time, but when i was on an 18, it felt very, sluggish downwind compared to my 16. I would say, get as much experience as possible and keep checking this site to gain more knowledge of the sport, trust me, it really helps...well, good luck with the sport!!
