Iron Cross combined with Come Bets?

Ok I know that the Iron cross system does not pan out. My question is, how do my odds change if I also put down a come bet? I am slightly leveraged if a seven drops and if any other number hits I can take odds on it (except 2,3,12) but then my field bet pays off double 66% of the time on those incidents.

If the 5,6, or 8 hit, I can pull my place bets and take odds on the come bet, limiting my exposure and maximizing pays.

I am still somewhat new to craps but I was thinking this style might limit some of the downfalls to playing the Iron Cross style.

Thoughts, comments, advice would be greatly appreciated.

I dont know how your odds change. If I use the Iron cross I am usually betting bigger and only looking for one hit and then maybe I'll take the win proceeds to go up on the 6 & 8. It can get risky. I personally have never just stayed up that way for long, as you are risking the same 7 every time and the 5,6,8 are losing your field play while getting only even $ on the 4,9,10 & 11.

The come bet is a contract bet so what you get with hedging against the seven you could lose on the next roll with a seven or water down your field bet. I would avoid the come bet and just use it as hit and run. Do you normally play at 5, 10 or $15 tables?

I usually play $5-$10 tables and just increase if I am winning. I know some people use the iron cross method only when the come out roll is 5,6, or 8 (mainly the 5). The idea in that situation is that you only have to place two #'s and have odds on the point(hopefully 5, but maybe 6,or 8).

The reason for the come bet is to limit your loss marginally when the 7 arrives. It may be a small amount but just may tip odds in a better favor? I understand that the come bet is a contract bet but the odds are not, so you can turn them on or off at your leisure(if you play that way). It seems like the house edge would be lessened if 6 out of 6 rolls the player gets paid something. Plus the chances of a 6, or 8 are fairly good and when you replace that place bet with the come and the odds, you are in a better position (speculative?).

I am not sure if this is a sound theory that is why I posted to get all of your guys feedback
