I love using low profile reels for smaller rivers, but now that I fish a CP unless I'm fly fishing, I only use them for throwing spoons and spinners. Abu Garcia makes a few OK ones for a good price, but Shimano has some really good low profile reels. I like a lower gear ratio because I don't like slow retrieves. If jigging a spoon (or swinging it) or a curly tail, low profile reel allow me to retrieve and jig with my index finger and fish with one hand most of the run. Also allowes me to have better casting and line control, doesn't take as much a toll on your arm as biggest bait casters.
For larger baitcasters, I own 2 Luna 300's, great reels, but now that I do not fish the Fraser they just collect dust. I only use them for bar fishing occasionally, but there are far better rivers to catch springs with no crowds. Smooth casting but you get tired casting them a lot, especially bottom bouncing.
