Profiling Banks For Roll Hunting

Does anybody profile their banks in regards to roll hunting ?
In Canada, we are very lucky since most banks are part of national chains. I usually rotate through about 30 different branches in my banking chain (RBC) over a period of several weeks. I am very impressive how polite all the tellers are, even though it is not my branch most of the time, when I am asking for coin rolls.

I found banks in wealthy neighbourhoods, in tourist areas and near major shopping complexes are where I get my best roll finds.

1) I find a lot American coins. I like fooling myself into thinking the 25% premium on a few dollars of coins pays for my gas for trip.
2) Older coins (pre-1965) and silver coins
3) Rarities like 1970 (5&10 cents), 1991 (5 cents), 2000P (5 cents), 2006P (pennies), etc

I find roll hunting at banks in poor neighbourhoods lead to rolls that are well picked over (usually no silver, no American and no older coins). In poorer neighbourhoods, commemorative coins (e.g. 2005V nickels, 1967 pennies, etc) are also well picked over . Fortunately, rarities are still found.

Usually, after I have been to the same bank on my list 3 or 4 times,
I decide (based on my previous finds) if I will visit it again or not in the future.

Surprising, I am finding most of the rolls at all banks are not heavily picked over. I typically still find 50% in pure copper pennies (pre-1997) and 20% in pure nickel coins (pre-1982), indicating that not too many people are hoarding base metals.
