I haven't tried the Sniper, but I wouldn't recommend it as a first creeker. As Dan mentions above, it's a specialized, low h2o volume, steep creeker. Probably too slow for the type of things you're going to be wanting to try as you break into class V in CO.
I'd recommend something longer. I'm not against Riot boats, just against a really short boat for the types of runs we have here in CO.
PS - I thought the Creeker 225 was a small person's boat (<150 #'s), too. I did clear creek of the ark and liked it, but did a 180 of opinion when I took it down pine creek that afternoon.
