Hmm. make sure you hit water features strait, and hard, was amazed at what my 11' culebra went through on it's last trip, lined up and punched right through. Was also loaded heavy. And catarafts tend to go through stuff a little better than rafts.
On that note, try and avoid the meat till you have a better feel for what your new boat can do, don't go followin' the big boats into stuff that will flip you. Ease into it with mellower runs first.
Also river rescue cources are awesome, I have been happy with my rescue 3 training.
Little boats are a great time, enjoy!
