Reducing graphical stuttering in RP2 tubes

[stringburka]

Yo all. I'm wondering if there's any good way to reduce stuttering in RP2 tube systems. More specifically, I'm wondering if there's any good way to "gather" the stuff floating around one and one and resend it as a stack. My current system is a peat farm that has four main things floating through the system - peat, bog earth, dirt and sand. All except bog earth are sent automatically when they're ready, so there's a lot of stuff going around alone. I've been thinking about having a chest where it's stored with a mounted output filter with a slower timer, but i'm afraid it'll get clogged. Any ideas?

I managed to reduce it somewhat by putting a pair of filter->chest->filter that takes single blocks as inputs and outputs whole stacks, but it only works halfway through and is quite big. Noone has better ideas?
