Re: I really am a nerd - I did a tripod/head test in detail
For sure a leaf shutter is better at long exposures than a focal plane, however...
Shutter vibration is of a frequency that renders the maximum deleterious effect at around 1/15th second in any system. As you go longer or shorter, the movement captured is mitigated significantly. When you get to 1/2 or 2x the effect, it is for all intents and purposes gone, or by 1/60th or 1/4th. So... Try a MLU shot with your Hassy at 1/15th on that same pod and get back to us. I suspect it will still be better than we can do with an FP shutter on that pod, but possibly not as good as I can do with an FP shutter on my more rigid pod
PS: Yes, I do everything possible to avoid using 1/15th when shooting, even will purposely choose a smaller or larger aperture or change ISO. I have even been known to mount my 3x ND filter to avoid 1/15th. Seriously...

I read this with interest as I just made some tripod captures for the high ISO thread...
The only tripod I had to hand was a Gitzo GT-530 (don't laugh!) which is their smallest and lightest travel tripod...
With mirror lock up and the camera+tripod combo on top of an old washing machine, I had no issue getting 2.5 second exposure with no shake. I did of course have no problems with wind!
Here you go...
That's a 100% crop of this image...
I guess our shutter is very unobtrusive.
Best,
David
