Entry fee tournament question

[WSOPstar2B]

At want entry fee break point do you experienced players feel that the fishes and donks are down to a minimum and the field is populated w/mostly sensible players? $50, $100, 200?

Then based on that break point, what should the bankroll be at to play at that entry level?

I know some of u also play SnG's. Same question above for those also.

Thanks!
