Best for what? Best is always highly subjective on any topic and you need to clarify your criteria.
We can't tell you that adding X as a TL will improve your odds of getting a "high" (also subjective) limit with CO. Your credit determines the limit that you qualify for with any creditor. It's not just a matter of specific tradelines and their age but of all the usual factors:http://www.myfico.com/crediteducation/w ... score.aspx

It's not just about number of tradelines. Creditors have varying underwriting criteria and we aren't aware of all the details for even one given creditor so we can't answer your question. Your entire credit profile needs to match the underwriting criteria for a creditor for such limits. If you have nothing then you have a lot of building to do. You can't run until you've sorted out how to walk first.
Get 2-3 starter cards. Build some positive payment history with them. Either they'll grow with you or you'll need to take some action to get them to graduate/grow and/or replace them with better cards. However, at this stage you need to focus on simply qualifying for starter cards and if you can't get approved for unsecured then you may need to go secured.
