FTP Double Points

I logged into FTP yesterday for the first time in a while. I noticed their double points promo from now thru Jan 5. I decided to take advantage in hopes of putting together some points for something decent from the store. I don't have a shit load of points or anything right now, but hopefully this will help me step my way to a new ipod or something.

I ran like hell again yesterday, but got about 500 hands in this morning and ran like normal. Just slow grinding. I've been playing full ring $25 NL lately. My no limit results have been fairly decent as of late. Why do I continue to waste time (and money) on the limit tables?
