Actually I said "full face motorcycle" helmet. AFAIK, there are statistics helmet riding versus riding without a helmet but not for full face versus other types. Or I could dig 1 layer deeper and say Top of the Line racing helmets (Arai/Shoei) versus other types. And in each case the best helmet you can buy is no substitute for proper training, experience, leathers, boots, gloves, etc....Anecdotally, I can say my full face helmet saved my face from major reconstructive surgery at least 3 times and my life at least once.
Anyway back to diving, I see logic in a few extra breaths, others do not. Anecdotally, there are numerous accounts of divers who used Spare Air to assist in an OOA situation. I could design a randomized study where I surprise turn the gas off at 70ft in typical dive situations with typical divers to see who fares better, the group with Spare Air or the control group without. Although obviously just a thought experiment, I know I'd personally rather not be in the control group.
I feel it's a personal choice where neither side of this issue should be critical of the other as long as the device is not used as a crutch to avoid proper training and experience.
You seem like an adventuresome soul. If you continue diving (which I hope you do) a few years from now you are going to look back and laugh at yourself for having had these thoughts.
It's cool tho. Everyone thinks like this when they first start out.
