imho it depends on which large folder ya are talking about, for instance while a cammilus cuda maxx/darrel ralph maxx 5.5" folder carries as well as most 3.5" or 4" folders something like a strider AR or GB doesnt carry as well due to being so much thicker, to me the thickness and weight seem to matter more than the length, so being thin and lite the maxx carries well and i edc'd one for several yrs.
that said nowadays the 2 knives i edc the most, a spyderco Ti ATR and a emerson custom CQC13 are ~ 3.5" and 4" respectively, and will imho do anything i need to do with 'em, i dont ever go below 3.5" though,
another good edc folder is the pat crawford perfiogo with a 4.5" blade, its also thin, lite & carries very well for its size.
if i was carrying a knife mostly for the purpose of SD i would probably go with as long as possible, but if that meant being over 4.5" or 5" i would probably just go with a fixed blade, or possibly go back to one of my maxx's.
the maxx, like i said before, really carries well for being a 5.5" blade, only con is cammilus versions are darned near as expensive as the ralph customs nowadays, but if ya want a long bladed folder i dont think ya can do any better than the maxx, i still have a cuda maxx stilletto and a ralph stilletto and also a 4" mini maxx spearpoint w/a talonite blade, the cuda maxx was only $150 or so IIRC when i got it i wish i woulda bought 4 or 5 of the things.
