I am currently feeding any excess Stone from a silk-touch Ender Quarry to a recycler, via AE2 ME system, no chests, no hoppers. Set it up and forget about it.
Now this isn't a pure IC2 build, obviously. But on DW20 1.7.10 I have almost 300k stone after dropping a 5x5 ender quarry. keeps the Recycler busy until i plant another one.
