Honnestly, I prefer a hybrid logistics pipes / RP2 sorting system. I much prefer RP2 bounce back mechanic vs. "drop items on the ground" mechanic from buildcraft. I use RP2 for input, macerating, smelting, and common bulk item sorting. The sort of stuff that, say, a frame quarry will be dumping stacks of at a time. Anything that my RP2 system doesnt know about gets kicked to a "random junk chest". All chest inputs are from the bottom. On the back of each chest I have a logistics chassis pipe; on everything but the overflow chest, I have a provider module and a polymorphic item sink. On the random junk, I have an item sink as default, a provider, and a quick sort. Usually I throw a dirt and sand terminus module somewhere in the system for excess sand and dirt from forestry farms.
The reason I built this was because of my first frame quarry (DW20 style) that completely overloaded my early pure logistics pipes system. A quicksort module ended up dumping lots of items on the ground, and multiple wooden pipes out of the ender chest ended up with a lot of ore in the default route not getting sorted.
