Hey everyone, I am planning on getting a jackson kayak package. I live in WV and plan on doing most of my kayaking here. I will mostly be doing river running maybe playing a little. I am 5'10 160lbs 17 years old and probably not going to grow anymore since my dad is only 5'7, im lucky i got to 10". Anyway I need help deciding btwn the jackson fun and the 4 fun. On their site it says the optimum river running for the fun is 155 and for the 4 fun is 160. Then it says optimum weight overall is 160 for the fun and 180 for the 4fun. I plan on only doing river running which should i get. What will be the pros and cons of both. Thanks in advance!
