When everybody's in the cruise, nobody's going to hit anyone (unless you don't see your VFR buddy coming 175° out, straight at you at the same hemi level
). The reason for
monitoring the Area freq is because IFR will call on it prior to entry into G (dunno why they don't broadcast when leaving C at WATLE... it looks to me from way over here they should, but then again, there'd be a good SIS there, would there not?), and if IFR are cruising in G, they will call prior to changing level/descending. IFR departure from G? Yes, we again make a call on the Area prior to takeoff, and then again on departure. VFR can then pick up my calls and decide if they will conflict with me. If VFR are close to/"in the vicinity of" the airport, they'll hear me on the CTAF when I give my "recommended" calls.
So, what frequency will the IFR be transmitting on? The charted frequency. This conspiracy theory about frequencies on charts forcing VFR to make full position reports or pull out an IFR chart to see where GAFFA is, or whatever you're going round and round in circles about is just plain nonsense.
