Might want to get bet105 on your list. Still new (appears a buyout and reopen from heritage...had $50 limits previously, now same limits for all, even sharper players), only 1 payout but smooth and quick. Remains to be seen if they keep it up. Openers very similar to Pinnacle.
How MB and US are that high is beyond me. If you prove you can breathe, limits cut very quickly.
Agree with above comment...BM and Betonline/LowVig all by themselves on top of the offshore world (unless you live in Canada...then clearly Pinnacle up there). Betany not in that tier, but they do pay.
