I'll admit to disliking the two-tapes-per-side thing. As far as I'm concerned, it's a cop-out made pseudo-necessary by the fact that there are so few sizes of adult diaper, and so little elastic in the waists. Basically, each adult diaper size targets an enormous range of body shapes/sizes relative to the baby sort, and since there's no elastic to allow these diapers to conform to your body on their own, you get a bunch of extra tapes and have to do it yourself.
Blech!
Of course, the alternative would be more expensive.
Folding your way to a one-tape-per-side diaper seems totally workable. I haven't tried it myself, though. If your diapers are a perfect fit when worn the normal way, you might want to buy a size larger if you plan to do any folding. Otherwise, once you've pulled the back of the diaper up high enough to ensure that the level of the lower tapes is above your hips and butt, the front of the diaper may be too low.
