We've been running a 1460 Axial Flow since 1996 in the UK, a couple of years ago we fitted the newer speciality rotor to it so we have a good idea of the difference between the two. If you want to know more about running them you could always e-mail me and Ill give you my phone number and Ill fill you in with the details. The primary reason we purchased the Axial Flow initially was the price but after running one I wouldnt really want to go back to a conventional again. Derekjohnston@precise-solutions.co.uk
