Baitcasting reel Vs. spinning reel
the reason they are a must is because you need to stay in contact with the bait throughout the cast. If you tried to cast a spinner bait on a spinning rod, the bait would sink into the weed before you had a chance to get the slack in. With a baitcaster, I can halt the bait just as it hits the water and start retreiving it stopping the bait from sinking farther than 3-6 inches below the surface. It hit and starts swimming immediately....
Couple things here....1, I highly recommend getting a decent baitcasting setup. If you want to start out cheap, go to walmart and by a blackmax combo for $60. It'll be worth it, and it won't cost much. Just do a little QA while you are in the store. Make sure the reel has all it's parts and the guide line up and feel the rod for cracks, nicks and dings. If you do that you'll have a great rod for your first season using one.
2, it will require practice. Lots...... and I recommend also for the first season that you load up your reel with line that's too heavy...like 12 or 14 lb line...Yes it's too heavy for skilled fishing, but it will help you learn to cast. If you want, tie on a 5 ft long 6 lb tippet/leader on so you have lighter line out by your bait.
3, after you get the hang of it, you might foresake all your spinning tackle. Baitcasting is that awesome...most people who don't like just didn't have the patience to learn how to use it well. Practice 30 minutes a day in your front or back yard until you can cast 1/2 oz lure about 50 to 75 ft without backlashing.....then you can go fishing.
Here is an ok line guide link for each fishing application. They clearly love flourocarbon which I am not the biggest fan of.
I use 8-10lb mainline and a 4 or 6 lb berkely xl mono tippet that just reaches the reel during a cast. The only break off I got this year so far was a pickerel that cut the line with his teeth last week. Actually that was on my UL setup with 6 lb mainline and he cut the 4 lb tippet.
I fish a lot of clear lakes and have had no problem catching fish that are supposedly "line shy". Flourocarbon has waaay to much memory for me and I'd rather use a line that I don't have to rub down with conditioner in order for it to work. Also I have had waay to many breakoffs when jigging the bottom for me to trust it. Simple Trilene XL or McCoys mean green is the way to go and mainline power pro for most bottom bouncing presentations.
flouro is not just less visible, though that is one of the characteristics for it, its not the only difference, and like skunk i am also not a big fan flouro
