I only used spinning reels growing up. I remember trying a baitcaster a few times, but never could figure out what all the fuss was about. I finally got the itch to learn how to use one last year and bought a Lews Wally Marshall and a Lews 7' M LS Laser rod. I spooled it with 14lb Big Game Trilene and hit the water.
First off, the reel is pretty inexpensive. I had no idea at the time that it was a reel designed for Crappie fishing. I had a friend set up the drag for a 1/2 oz spinnerbait. I would spend at least 15 minutes every afternoon practice casting. Mainly, I was trying to focus on accuracy and distance. I got the hang of it and started working on familiarizing myself with the drag system and how the setup would cast different weight lures. I still don't have it exactly perfect, but I can go most of the day without a backlash. I grew so used to using it that I drug out an old Abu Black Max reel and took it all apart, cleaned it, and put it back together. The Black Max is an older inexpensive reel, but it works amazingly well after the cleaning. I bought a new Skeet Reese pole for it and spooled it with 40lb power braid. These are the only two combos I take on the water when I go after bass.
I still have a few spinning combos, but those are for catfish, bream, and crappie only. I doubt I will ever go back to using a spinning setup for bass unless I'm going for a finess approach. It does take a little bit to get used to a baitcaster, but if you stay at it, you will love it. Lew's has several very good inexpensive reels. I love their new BB1, and hope to get one someday, but I don't feel like I have outgrown the capabilities of my current reels yet.
A little tip on digging out a backlash: There is almost always a little loop of line right below the snag. If you can find this loop and pull it out, 8 times out of 10, you will be good to go. Also, at first, stick with a good mono line. Flouro does not like backlashes or kinks. A kink or knick in the line will usually result on the line breaking there. Try to stay away from braid at first, too. Braid is pretty forgiving, but can make for some nasty backlashes. Don't buy Spiderwire ultimate Mono. That stuff sucks. Hope this helps you get started. Realistically, anything you want to know about baitcasters can be found in youtube videos or online reviews.
