Count another pro-flow vote. The flow can be done more at your own leisure, whenever you get a chance, and the same goes for the other crewmember. Consider rolling out after landing at a busy airport with a short taxi to the gate. The PF can be taxiing and navigating with his head up, etc, while the PNF can talk to tower, ground, ramp, and company during that short taxi. Meanwhile you've both almost instincually accomplished your after landing flow with a couple quick swipes of the hand. Thus despite being really busy you aren't taxiing in with several thousand watts of landing light blazing, the flaps aren't dangling, the anti-ice isn't overheating - all these benefits without having pulled the checklist out yet. Once you get some peace and quiet, you and the captain can mentally "get-together" again and run the checklist real quick before you park. This is in contrast to being heads down in a dolist while the aircraft hurtles off the highspeed and into the fray of taxiways.
Thats the beauty of the flow, everything is actually done, even if you and the captain are mentally/verbally separated because you're on different radios/PAs, paging through charts or performance data or any number of distractions. Then just accomplish the checklist once the crew has a quiet moment together.
