Maybe one more item of interest to report. It seem not to well known that SME makes a higher mass (+30gr) counter weight. This ain't exactly cheap being tungsten and all plus it comes in the actual housing, even though one might argue that the tungsten insert alone could do just fine (it would stick a bit out of the cover though, not perfect enough for SME? I guess so.)
I have followed the DIY advise of my SME dealer and got some Mag-Wheel (lead) balancing weights, flat lead pieces with double sided stick tape. Made some to fit, easy enough and added 30g to the standard weight -- seems to work just fine, till I get the notion to spend some 400$ on the real thing.
It has the effect to increase the effective mass of the arm and it might be somewhere plus ~ 2gram now. The standard weight, depending where it happens to sit, renders the effective arm mass between 10 - 11 gr.

PS: once a V arm user always a V arm user? Well, we'll see...
