Zero. IMO.
Some of the best advice you'll ever get in your life, you'll ignore. That's the case for each of us. With that being said, I think you should avoid future .US registrations and all other non .COM and non .ORG names.
If you want valuable domains, you will need to buy valuable domains. That means investing in quality aftermarket premiums. Go ahead and delete this name along with all the domains in your signature and start over from scratch. I'm not saying this to be mean, I'm telling you this to save you a lot of wasted time and effort.
Good luck, and may the force be with you!
