In this case I would try to make 1 NL buy-in around 25 Big Bets.
If you’re playing with $50 buyins that means 1/2 w/ 25c BI
If you’re playing with $100 buyins I would make it 2/4 with a 50c Bi. This structure is also much better for a .25c ante.
Buy-ins for our crew will average in that $50 range. Some more, some less. Most will rebuy but not all. I think for our game the 1/2 limits would be the most appropriate due to that buy in range.
