I get your point, but for your #3 - Perpetuum, the nuts and newtons might do the job as well in terms of fueling for a short-long-ride (like 4 hours or something) but if you're really riding for a LONG time (many hours to days) I think you can end up with more gastro problems because your digestive system can't deal with all the other stuff like fiber, and your digestive system isn't really working that well anyway b/c all your blood is going to your muscles, and because you need so much fuel it gets overloaded.
I don't do really long rides, but even for my medium ones (6-8 hours on the bike) if I'm riding hard I can't eat all "real food" - I need to use some gels and sports drinks and some real food. Otherwise I get too much not-completely-processed food in my system and have stomach problems.
Everyone is different for this, so experimentation is key.
