The one I linked has a taper for nutation as well. The point of the no corner radius escapes me. Seems like that would mess up things more than help.frank828 wrote:from what i remember, it's not just the size that was unique. The base had no corner radius so the edges are almost knife sharp. Also there is a bit of a taper to allow for nutation.

Perger asserts the knife edge taper is to eliminate the vacuum effect of tamper uptake. So the puck doesn't get sucked back up once tamped. The implication being that even a micro suction effect has an impact on the extraction. I have no idea if this is true. Just reporting his claims.

Awhile back they changed the Strada basket wall finish to prevent channeling on the sides. I think the new basket has matte finish.
Not sure if this applies to VST though.

It does have a matte finish now. Side channeling was the only form I got, I never got donuts or spraying, dancing blond cones, just spurts along the outer edge
