Minitor V and Scanning Simulcast Channels

So I have a question in regards to the scan features of the Minitor V. Reading old posts, a lot of people have asked questions about scanning 2 different frequencies, one for fire and one for EMS and how to get the best of both worlds while not missing pages. I understand that in that scenario, with silent scan, you get whichever one tones first, with priority scan, you get alerts on F1 only but will hear audio over F2, and on probability scan, you get the same thing as silent scan but your squelch also opens on any traffic.



So my questions is, how does this change if there are 2 channels being simulcast? For example, having an East Tower that transmits on F1 and a West Tower that transmits on F2. Which mode do I want to prevent missing pages?



F1 is the main tower, and F2 is a lower powered repeater/simulcaster. When in the western reaches of the county, F1 can pickup outdoors only (not in vehicles or buildings). What happens if I'm close enough to F1 still for me to pick up some static, but I actually want to hear something on F2 since it'll actually be intelligible?



My thoughts:

Silent Scan: Would be the 2-channel equivalent of Selective Call. Probably the best solution to keep the minitor silent until the right tones are received, but I'm worried that if the fidelity over F1 is too low and it's picking up static, then it won't release F1 to go scan F2 and pick up the alert over there. Or vice versa.

Probability Scan: Would be the 2-channel equivalent of Monitor but if you got static on one channel, it wouldn't release that channel and go to the second channel to listen for tones.



The only solution I currently see is to program a Priority Scan for F1. If you hear nothing but static (or a brief audible voice but then static as F2 switches over to F1 since it's the priority channel) on Priority scan, then you can assume that F2 is the channel you need to be on to hear clearly and you can move to another switch that is "Monitor F2." The biggest disadvantage I see to this is that the stored voice would never work on F2.



Anyone have any better ideas?
