Buy some cheap line and back all your reels so your new line is about 1.25-1.5 casts long.
That will save a bunch of money and line.
Fish braid when you can (ie jigs, frogs, whatever else) b/c as mentioned above it can last all season. I like Power Pro.
Try the Stren Flourocast, it's like $10 for 200 yards. I'm sure you get what you pay for...but I know it works b/c I've used it and the price is right.
