I've been riding a Kodiak 400 for the last 7 years and recently purchased a 2009 Grizzly 550 EPS. Here's the kicker, I am out of state until the end of May and have never even ridden a 550. Most of the traffic on this board seems centered around the big bore machines and I'm starting to wonder if I'm going to seriously regret not getting the 700. My 400 got me in and out of the bait station, moose camp, chitna, chicken, and countless other places. I figured the 550 would be as much machine as I would ever need, but I'm wondering if I'm really missing out on something by not getting one of the big boys. Is the power increase from the 400 to the 550 going to enough, or is it just going to wet my appetite for more?
