Pocket carry is necessary at times but in my experience it isn't ideal for a daily setup.
IWB's are great and I use them regularly. I have to go up in pant size and a notch on my belt to make this happen. If you're going to carry two, you're gonna have to widen things out even more. And I assumed you'd have to be capable of drawing either left or right handed? And if weight is a consideration you'd have to add in the weight of whichever AIWB holsters you opt for.
I do not know who Mike Pipes is but the notion of dropping empty revolvers and grabbing loaded revolvers sounds a bit unorthodox. And time consuming.
