here is a picture of the old portafilter flanges vs the new /B flanges.. My cut portafilter is the old design on the top and other is the new portafilter that came with the /B machine beneath it. The new portafilter locks in VERY TIGHT, you cannot twist the handle past the middle. It is as tight as my old Rancilio Silvia. I believe Breville has solved the spinning out problem with this new portafilter design.

funny, I find the top basket holder just ever so 'more elegant'. Here is a perfect example (If we have the right of it) where esthetic may not point directly toward engineering functionality. I'm sure the project engineer who worked it up is having one of those moments too. Heh, but... what if we left the first design but only polished it with a 400 grit dry and not the 1200 wet? c'est la vie!

I can now confirm the design of the grouphead is the same on the /b model and the older model. I took the new /b portafilter to Sur La Table and screwed into their older breville dual boiler. It screwed in tight. For those who have spinout problems it appears all you need is the new /b portafilter to solve the problem.
