My Honest opinion:

The fact that you were able to use all three successfully points more to the probability of the ubiquitous walled-up house shot than the utility of those ball as a shot changes. Normal oil pattern changes, even those for a house shot, would not normally allow you to use such a wide variety of balls. It also points out that you probably could have used any one of those balls all night, just as successfully, with feet position and target changes.

Besides all that, great bowling to score that high even on a house shot. Congrats!

Nah, Scott. Even a lefty doesn't have that much leeway on oil. I think this may have been an extraordinary oil pattern, one of those ideals,on which we less than capable bowlers dream of being able to score.

(My last game last night had 4 ten pins, 1 nine pin, 1 four pin, 1 seven pin and 4 strikes. Now I know I am not a great bowler and I didn't flush the pocket, but most of those were in the right neighborhood, with lots of pins moving on every shot.)
