I do dealers choice with .50/.50 on big bet. I go with .50 ante, $1 bring in $2/$4 fixed limit when stud mixes in. It feels comparable, if not a little small, but our big bet games have a reputation for playing larger than the stakes would suggest. $100 max and it's rare we don't crack $2k in play 6-8 handed.
We don’t ever get close to that amount in play. Usually around $700-$800 on the table. This makes me think the $1/2 limits would be appropriate for us.
