TITLE: To raise my credit limit or not to raise my credit limit...
POST: **Background:** I'm 24, I have two credit cards, one being just a few months old with a $500 limit, and the other (the one in question) was opened in Aug. 2007, and has a limit of $300 (had with $500 once, dropped to $300 in 2010 when I was in school and there is no record as to why). I always pay off any debt the month of, and my credit score is between 700-720 (checked a few months ago, but I have opened a new card since, and two landlords have checked on it). 

**Question:** I want to raise the limit on the $300 one (from 2007), but I'm not sure by how much, or if by doing so I will hurt my current score. It would be great to be able to make larger purchases to redeem those points, as well as not be hurt by over utilizing my limit (not that I leave a balance on them for very long anyway, but I have been hurt by it before.
TL;DR: 
Should I raise the limit on my $300 limited credit card, and by how much? My credit scope is 700-720 range and I am 24.
