Either from top or bottom is about the same effort... you need to remove the lower belly pan/cowl either way, and you're down there anyways.
Using a filter with a bigger volume won't affect oil pressure, if anything all it will affect is the duration that the oil pump sucks dry after an oil change (longer duration). Which begs the question, is the increased particle holding capacity worth the increased initial start up bearing wear? Doubtful.
For the guy asking about RP, i have never used it in my engine but i do use it in my tranny (75W90) and i'm happy.
