Hi Zach, I see this was your first posting, so welcome to the site.
You being on limited budget means you have to be careful what you ask because the Bait Monkey is ever lurking to pry your wallet open just a little bit more. Believe me, I know.
That said, for now you can stick with your Fireline. I'm not a fan of it, I'm a fan of original Power Pro. I actually have 10lb Fireline spooled on one of my Stradics at the moment. But as roadwarrior suggested, for a cool $5 you can try out 12lb Tuff-Line. I bought it, but I have not spooled it up yet. The line gets good reviews so far.
As well, I assume you have a spinning setup? If so, then I feel braid is absolutely the best for line management. Tie on a leader -- be it mono, copoly, or fluorocarbon. Personally, I use copoly the most. It is inexpensive, and some are coated (P-Line floroclear, fav) or blended (Yo-Zuri Hybrid) with fluoro. They are extremely strong.
Become proficient at the Albright - or modified Albright knots for joining braid to leader. Of course, this is my opinion. I like the slender profile of the Albright knots the best, and it is incredibly strong.
