I've got bugger all experience in no-chilling/cubing as I really only started doing it last Easter to any extent. My two kettles are large enough to 'double batch' but I never want to ferment 2 of the same beers at the same time. I used to get around this by having another brewer over and we'd do a few brews and have a fermentor each. Had a situation though last Easter where I wanted to do 12 batches (six side by side double batches) to investigate some BIABacus number stuff and to fill my then empty fridge.
Cubing half the wort and chilling the other half worked out really well time-management wise. It's an easy way to get a lot of beer out of a brew day if you have a large kettle.
As mentioned, I have bugger all experience at this but leaving the cubes for this long doesn't worry me one bit. I've read or talked to enough other brewers to know that, fingers crossed, there should be no problems. I can't wait to see how the lagers go. The chilled portions of those brews both got silvers last year (no 'molly-coddling' done on them, just good solid recipes from 'Brewing Classic Styles') but I am hoping that this longer time in the cube might do something interesting to them. Who knows? Am kegging them this weekend.
The only negative I have on no-chilling (or delaying turning on an immersion chiller, plate-chiller etc after flame-out) might not lock in the flavour and aroma hops as well as an immersion chiller employed at flame-out. This doesn't matter as much on something like these lagers and I know there are ways around this but I never have the time to explore them

.
Because I had almost zero trub in the cubes, the next time I brew, I am only going to transfer the no-chill bit immediately at flame-out so as I can start my immersion chill at 5 minutes rather than the 20-30 mins I delayed on prior brews. Who knows if I'll notice a difference?
Sorry Bob, what was your question?
