Cat 308C CR

So Im looking at possibly changing things up this year, and going to move some iron. I'm looking at a cat 308C CR to trade my 110 on, may put the 70SR with it to try and get the numbers closer to where I want them. Anyone have any input on this machine, good/bad? Is it fast, slow, smooth, jerky, weak, powerful? I'll definitely go take a look at it and run it before I do anything. I was looking at a 307C also, but I like the short radius of the 308. Thanks for any input! :thumbsup
