I used to be a tool junkie as well......but all that gets you is time spent fiddling with tools instead of doing things. I honestly think that if you would use paper lists for about 3 of 4 months you would develop a better understanding of the method which would then help you in finding the right tool. I am an Omnifocus user (who did buy a Mac just to use Omnifocus) but periodically I have to move to paper for a while just to clear out my system. All the things that make it easy to add items to your list (converting email to a task etc) also make it easy to add items that should not be there. It is also easier not to clean out electronic systems. All you really need is a few lists. Any tool can give you that. After you understand that, it's just about picking one that makes you smile.
