On the monty there is only a coaster break. I rode a few times in town
(Copenhagen/Malmö) on that bike and found it dangerous. The reaction
time and strength of the braking depended on the position of pedals.

On the momty that was no problem at all.

As long as there is no largish play (spiel) in pivot it should be okay.
I am convinenced that the extra friction will not be noticed at all. The
pivot on my own pivot has been in bad shape: dimples (index steering),
cracked cups, abuse from my side (over-tensioning of the bearings :-[ ),
and it all didn't feel like anything unusual when riding. Probably the
forces on the pivot (legs that steer, self centering) are so
overwhelming that it doesn't really matter.
