Thanks for the update! I'm also running a direct line to the airbox and have experienced excellent engine performance. But in my case no residue in the airbox catch tube.
Running the crankcase vent line run directly into the airbox, a little oil in the airbox catch tube is 100% normal. I would even say it's a good thing. If oil contaminants get that far, lighter fuel vapors are almost guaranteed to as well.
Your Blackstone results will tell the full story. If the fuel level in your oil is the same or less than other RX3s that were using the OCS (about 4% fuel), then that's a strong argument against using the OCS and pouring out the catch tube all the time.
