Deciding between the 1.5 and 2 should take in consideration what your desired use is, rodeo or river running. You would likely throw around the 1.5 and feel masterful. However, the 2 Fun would truly be a better river runner size and, in general, is the optimal size for you. A recommendation for you, though, is to first consider the Wave Sport EZG 42 as an even better river runner/playboat. For several reasons, I am confident that you would excell in it as your one boat for maximum appreciation of the sport. Enjoy!
