I like your list. The only one I'm not convinced n is Ripple. I own it, and have down for a year or more, but I'm not as confident it'll be a long term thing. The others, completely.

I've always been big on MAID because I love the project and idea behind it, price wise it isn't great at the moment, but they're working hard and testing thoroughly...which they have to if they're to achieve what they've set out to. I feel it's undervalued at present.
