The 225 would be way too small for you if you actually wanted to creek it. You really want the right amount of volume for resurfacing and staying on top of the water (in control). You may want to try the Huka, M3 233, or the small nomad. I can set you up with a Hucka demo up in summit county if your in the area or else there is someone down on the front range that can get you into one. I paddle the Huka and it is one of the best all around creekers out there.
Do yourself a favor and get a Salto if you like blowmoulded
I just happen to be selling one suprise surprise. Anyway the Salto is the best thing to ever come out of Germany let alone Prijon or Eskimo. By the way if you dont intend to run anything big the 225 would be a good boat at your size but when the volume comes up a small boat can be scarry. It really just depends on what you are going to be running Class 4 or Class 5!
I personally think that the 225 would be just fine for your size. I'm 6' 170 and, though I now mostly boat a Gus, have paddled lots of class V in a 225. It all depends upon your style of paddling. I found the Prijon to enter and resurface very smoothly on big drops and even though it's short it tracks like a much longer boat due to the keel line in the bow.
However, these comments are in regards to CO boating. I don't think I'd make a 225 my only creeker if I lived in a big water state like Cali or Oregon.
Thats deffinitley wierd I have had a couple of nibbles but I dont think from you. Anyway The boat is available to check out thursday of this week otherwise I will be in Lyons tomarrow then headed to the Poudre for the weekend. I will give you a buzz tomarrow and we can talk.
