Back in the 70's I ran a Big A and was kicking around buying a 6700. I have heard they ride rough but I wonder if they're trying to run 12 mph plus. I envision running 6 to 8 mph. Also do they use Hardi Boom plumbing. The pictures look like Hardi style boom but with Dry (hoses) TeeJet nozzle holders. I have like 6 sets of Hardi converted Nozzles.
