Not very 'original' or 'unique' but I'm enjoying a cold water shave with the Proraso green soap and the matching aftershave and then balm. Also if feeling brave, the Fine Accoutrements Snakebite.
I don't tend to change anything but I do prefer a blade with a lesser edge. Also find my skin is more open to weepers in this weather so I don't go overboard on trying to obtain a perfect BBS. More an OMA (Old Man's Ass), but happy.
I don't change a whole heap, except for showering/bathing in cooler water. Purists will bleat (and I blame my father here) but my brush ALWAYS goes into boiling water whilst I wash and prep my face. I've said before that, if anything, I can use my most aggressive blades/razors and drying soaps in summer. Maintaining a decent lather can be an issue with a sweat on ; I finish with less balm.
