Definitely plenty of bank for the 25/50c but if you get any kind of a crazy $1/2 game, or play PLO games at all it will run out of chips easily. For a $1/2 game I would want 400 $5’s and a second barrel of $100’s to cover big nights.
$5330 bank seems good depending on how splashy the 1/2 gets. But if it’s the same group that also plays .25/.25, like mine, everyone plays super tight when we play the higher stakes and this should be fine. If not and it’s a splashier group then maybe another barrel or two of hundos.
