Looking at my credit report this morning, I found a notation for a BoA MC I didn't even realize I had! A look in the file cabinet turned up the cards, not activated. I have had the account since 2000 and never used them(filled out an app at a STL. Cardinals game for a free shirt-hows that for a perk!) so I just filed them away(they are current cards expiring in 2009).
My question is, how do the Worldpoints compare to the Thank You Network? I already am racking up the TYPs but need another card for some other expenses and I have a rather large credit limit on the BoA compared to the Citi PPE. And since I already have it it won't be a hit on my FICO score-it's just over 800 and I want to keep it that way. How easy is it to actually use the Worldpoints?

Thanks.
