I agree this is not a standalone strategy. I'd call it a gambit. I use the field this way sometimes (usually with smaller bets) when nothing else works and I want to get in or out fast. One parlayed field bet can be super useful if it hits. As always, thanks for the great ideas.
I like the strategy..but very risky. I think i might have a change to this that you may want to try out. Start your 80 field to 160 across. Then instead of taking your first 3 hits. Take a number down until you have only the five six and eight left. Then use that to play yojr field strategy until its over. This way as soon as you hit your first point and take down a point you have none or little risk playing your second roll
