Well I've got the 028 Super rebuilt and got a new 18' bar and chain for the 036 pro. I decided to see how much difference there was between the two. I am running low kickback chains for now, until I get used to the saws. I was quite suprised that the 028 seemed really close in power to the 036. This was just by feel and not timed. I was bucking emerald ash borer ash 12" to 20" dia and maple of the same size. But my 028 does truly run like a new one now. I am going to have a tough time deciding which to keep. I still have the Homelite VI Super 2 which will now take over on limbing duty.
