What's wrong with wirenuts? They are about the easiest things to use of anything. I would NOT use crimp conns. on household wiring. They are made for automotive and other low voltage use, and in all honesty, they are crappy for that use. When I wire something in my car, I use small wirenuts. They are easier to install, cheaper, and less prone to corrosion. I like to fill the open ends of wirenuts used on a car with clear silicone to keep water out. I really do not understand why you want to use cromps on home wiring, and additionally, I doubt they are legal according to the code. Use what the code says. If you use crimps and have a fire, your insurance might be rejected fro having non-standard non-approved wiring.
I suggest you forget this whole idea and just continue to use wirenuts.
