140M cap in ATG

How well does the $140M cap work in ATG with 12 teams? Are there any issues with changing out players once the season starts? Was considering doing a $120M cap, but I'd rather not have to make a custom league and lobby for people to fill it.

I play 140 almost exclusively. It means it's harder to get the guys you're after but the player pool is very deep. I would recommend it. One can build decent everything , which means everyone can build decent everything. I haven't seen to many 100 win or 100 lose teams. These leagues seem to be tighter than lets say an 80 or a 200.
