Pinnacle Highest Limits plus for a big better its better to get lower juice on bets than signup bonuses. The savings works out to be way more.
DSI - Good bonus, high limits, loyalty program. I have used and known them for years and they have never thrown anyone out for winning. Plus I have a good working relationship with them so I cna always help out should something arise which I doubt.
These would be my 2 choices. Others you could look at is Betcris who claims to never throw anyone out for winning but they are working partners with DSI so its better to go DSI. Bowmans is another old solid book you could checkout
