Your post is a bit confusing AiQ, because you start off saying you are paper cash broke. But you have money in the bank that you could either wire to a casino or just go withdraw the cash you need. So why not do that?

I have no idea what you do as far as casino play. Are you comfortable with the casinos having all that financial information on you? If so then a marker is just about convenience of not carrying cash. But you have never needed (or wanted) that before, so why now? I can only speak for myself, as a lower mid limit player, I want the casino to have as little info as possible on me.
