I haven't read the entire thread but here's my .02
If you 1. eat a true human diet, lots of fresh fruits and veg and some occasional meat, nuts, berries, etc.... and 2. you squat all the way down when you poo and 3. drink plenty of clean water: your poo will come out like you've never experienced before and there will be virtually nothing to wipe.
When I was in Prague the toilets there are very low to the ground and they have a very wide rim and a really thin little seat. The bowl is very deep. When you sit on it your butt hangs down into the bowl and you are in a squatting position. When I was there I was eating very well (as described above) and when I would poo it was glorious. I mean it, I looked forward to a nice dump every single day. It's an amazing difference to poo in the proper position. It just slides right out and if you're eating right it's a nice well formed bm. When I was done it would be one wipe and nothing left on the tp at all. I could have forgone the wiping but it just didn't feel right being so used to it.
When I came back to the US I looked all over the internet for this kind of toilet. I'd grown so very fond of it I had to have one. Well there was nothing on the market here at all.... The only thing even remotely close was the Squatty Potty, it's just a simple stool you keep around your toilet when not in use that you pull out and put your feet on. It elevates your feet and puts you in the proper human squatting position when you poo. Works. Try it. If you eat right and squat no tp needed (I still use it but again, one wipe and done.)
