Thanks Rob!
interesting, to see the different carriers, I picked up a couple of utilities today with the flat 2 blade disc type. I was a bit suprised that the 70 series Special 160 had the flat disc (as per bottom right); as the other one I have, has the same type as is top left in your picture.
Getting back to my original inquiry though it looks like 4 and 8 blade carriers are the ones to look out for... I imagine you would get a finer cut and more "air" movement with those. I'll have to check out the Mustang see which one it has relative to your pics..
