Thanks for the write up Nick.
I'm the same about the heftiness. The MF3 is very similar to the PROBX in terms of heft... minus about 500-600g. The main reason I was looking at the MF4 was as you said... shorter collapsed length.
I too have the rubberfoot syndrome, so I may replace the caps with the rubber foot/spike combo you can get for them.
Interesting I have two-left foot syndrome - wonder if I can get spikes for that 
:p
I need an excuse to sneak in there for a squizz
