I know the screw vs spinner has been discussed on here previously. When choosing I was guided by the late Hivemaker's post on the matter.
I think he had more experience than most on the matter.
I also know that ITLD, who certainly has more experience, than pretty much anyone, when it come to heather honey finishes his extraction process with a centrifuge. So even though capping go through a screw first the honey is still passed through a centrifuge to filter.
My ideal would be to copy this on a small scale with tangential/swing frame extraction and a screw to deal with capping and cut outs, followed by centrifuge to final filter. However I could not justify the expense of both a screw and a spinner. As both would have utility with capping other than heather there was little to choose between them for me in the end it was the fact that the honey coming out of the screw would still need filtering that swayed me to the spinner. Admittedly the basket on the centrifuge will probably need to be emptied regularly enough to slow the process down the I feel that is a good enough trade off to have a good level of filtration.
