Condensation season planning — quilt boxes and moisture boards, or the Derek Mitchell insulate-the-top approach?

Perthshire, seven years in, and every autumn I re-litigate moisture strategy with myself. The traditional camp: quilt boxes of wood shavings or a moisture board under the roof, absorbing and venting water vapour so it never drips on the cluster. Cold damp kills, so get the damp OUT. Then there's the argument from Derek Mitchell's work (the Leeds engineer who's published on hive thermodynamics) — that tree cavities are far better insulated than thin wooden hives, and that with serious insulation ON TOP, the warmest surface is above the cluster so condensation happens low down on the cooler walls instead, where bees can actually drink it in winter rather than being dripped on. In that model you don't vent the heat out at all; the 'condensing hive' keeps it. I've run shavings quilts for years and winters fine. But I insulated two roofs heavily last year, no quilt, sealed crown board — also fine, and they were noticeably quicker off the mark in spring. Anyone run both side by side longer than one season?
