I'm a true believer in SFM. that thing is awesome wrapped in a bacon cheeseburgerMuch understatement.
I really am absolutely amazed at how powerful this system is. I'm gong to push SFM to its absolute limits though.
At some point I will most likely combine the multi-sieve with having SFM deal with all the combiners too as soon as I figure out how to get the rapid item valves to pound the stuff with norse mithril hammers of thor at the same time But seriously, yeah, you will tax your system so bad pushing it but it's one of those things that is worth it. If only you could copy/paste your configs to SFM and it would be a dream tho after I thought about it for a while, I don't see that being very useful in 1.6.4 but in 1.7 with no ID's I think it might be easier for him to do that.
