Jackson 2fun

Obviously i need to try and get in one of these, but would i be too big for an older version of it?

I am 5'7 135-140 or so.

As a more playful boat it seems like it would be fine, but i wonder how it would affect general river running...

according to the jackson site, i am on much higher than the optimum river running weight, but am slightly more than overall rec weight.

but eddyflower.com puts me right in the middle.

listen to the jackson website, they are dope boats tho Im sure you will have fun!

Well...what do you mostly want to be doing with it?
If you're planning on doing more downriver stuff, then get the bigger one.
If you're going to be mainly play boating go for the 2Fun.
Simple as that
