I'm with casilleroatr -- i've started using less and less pure-AE setups and adding in more BC pipes again. Here's how my Quarry sorter/processor works:
Item Tess -> Diamond Pipes shunting the more common items (cobble,dirt,sand,etc) into DSUs
Anything not picked off by the DSUs doubles back and goes through another series of pipes:
Diamond Pipes dump ores into Hoppers which feed Pulverizers and Furnaces
The output of my Pulverizers and Furnaces goes out via BC pipes into a single ME Interface block, and into my network.
Likewise, anything that doesn't go into the ore processing Hoppers gets BC piped straight to the above mentioned ME Interface block, into my network.
So my entire quarry support system is free of AE blocks, aside from that single, terminating ME Interface.
I guess I just don't understand why you'd want to do that. I keep seeing 'AE isn't good for all that processing' (or variations), and I don't get it.
Why is your setup superior (computationally, emotionally, memory, processor, whatever) to, say.. quarry to ender chest.
AE system has import module pulling in a stack at a time (or a couple stacks at a time if it's coming in too fast...two import modules should work. I've never had to use more than one).
Cobble, dirt, gravel to go barrels with priority 3 using storage buses. A storage bus exists for some form of disposal (in this case, we'll use one of the new fancy compressors setup to make quantum singularity pieces..but you could just as easily make matter balls or just trash it). That's priority 2. The drives are priority 1.
You have two or three pulverizers, or the equivalent IE or mekanism machines. Each one gets some subset of the various ores in your game world. You might or might not want to process everything (TC aluminum, for example), so you don't always process. Some ores overlap (iron, tin, copper, typically) so that if any machine isn't busy, it'll pick up. You have 3 machines, so if you have more than 8 ores (likely) and aren't using a fuzzy bus for duplicate types you can spread out the excess. Same thing for furnaces, again using export buses..precision or fuzzy, either works. I like TE machines so that I can have them spit out of the bottom onto a conveyer (they look cool) and spit the results back into the system using the same ender chest from before.
If I'm doing AE full time, I'm not too worried about power, but I suppose if I was borderline on having available juice I might want to do it differently. I'm not seeing how your system is superior in any way. You just have more inventories along the way to keep track of, with the pipes and hoppers. I guess the AE solution is more expensive? I imagine that's fair..it seems to do more.
