Thanks for sharing! I'll give it a try! BTW is --queue 4 because you have 4 boards? Shall I use 2 for 2 boards?

That has to do with work queuing from the pool. I believe it is a leftover from an older version of cgminer that would run into work shortages without it... I don't think it is even needed anymore but I leave the option there as it's working well. If you do add it I would leave it at 4.
