We may need a new thread discussing balances you are comfortable having at specific books. I realize pending how things go, a rollover can lead to a significant balance if someone is red hot or even if you arb to roll the bonus, everything hits at that book. But, taking that out of play, might be an interesting discussion. I know personally I am constantly moving funds around (or out) to mitigate risk. A shop like ABC I might only keep a grand or less (prop limits suck so none now) where a shop like BetOnline or Bookmaker feels like a bank, but I still limit things to some extent. Also shops like BO that take withdrawals on weekends have more value than BM who is Mon-Fri.
