If you can afford a rebreather, you can afford gases, and you can afford to do it right. You have to take bailouts anyway, so you need small bailouts, which means you have to be good on gas, which means you must be able to do the dive without a rebreather in order to use the rebreather. You know damn well what the Rule means. Ther is no shortcut, no magic carpet - the storkes can't do the tough dive with any amount of gear, gases, logistical suport or anything else - you still have to do what it takes , and the hallmark of the stroke is his unwillingness to pay the price, hence the search for the magic carpet. Notice we do not ever see any of these guys getting anything done, but we hear a lot of promises, excuses, and BS. It is like what they day in the US about banks - they won't lend you money unless you can prove you don't need it. Don't use a rebreather unless you can do the dive without it. We did our long dives on scuba, and then used the rebreather to fill in the details of the map, getting good "dwell time" at distance without effecting our gas rules, and diving repeatedly over the same stages without using them. That is what I mean. We are not technophiles, we are just getting the job done anyway we can.
