I tend to diversify with MOF and BOF so as not to miss out on the last click. Does anyone have experience with this approach? What can I expect?

I've been using the following system for years for winter snow climbing: Smartwool base layer top and bottom + hardshell ski suit. Belay jacket for emergencies.

This has worked miracles for comfort and flexibility, and allows a ton of control over moisture buildup. But it's only viable in non-stop activity.

I recently went up, and the wind on the route was 40+ mph. Besides having to stop and brace myself frequently, which ruins the heat buildup I was relying on, the wind carried too much heat out through the vents. And if I blocked the vents to avoid this, I built up too much moisture, and the hardshell's outer temp froze it.

I highly recommend the system, and I'm sure people use some variation of it, but do watch the wind forecast as well as precip and temps because it can be as defeating as forgetting boots or crampons.
