You will never beat craps on betting strategies, you mention you like the don't pass and also that hardly any tables/shooters are ever hot. This may be true, but how many times do you lose on the come out roll with a 7? Believe me, it is IMPOSSIBLE to beat craps consitently by just playing on any hunches or strategies.
Craps is beatable if you can control shoot, but that takes tons of practice and I don't want to get into the specifics of control shooting here, there is other threads on that already.
I suggest to work, build a bankroll and practice card counting. You can at least play with an advantage unlike craps. Don't go into it with the idea that your going to make hundreds of thousands of dollars and be able to quit your day job. There are very few out there doing that.
