Yep, got a couple 660s in the bunch and they're real close to the Prairie. (my second choice) As we've discussed before, I don't care for the IRS and that is the main difference in these two in stock configuration. Plus the Prairie can be modded to do things that just ain't normal. The more power the better.
Mark, the only pictures I have show the thing up to the seat in the swamp, but I'll dig up a couple and post um later on if you want.
