My current thoughts on bait casters & rookies. If you're going to lead off with a Curado or SLX DC, I'd get one of the lower gear ratio ones and focus on throwing reaction baits, like cranks & spinner baits, stuff like that. I'd use a cheap mono to start, then when I thought I was past the frequent backlash stage I'd go to a quality co-poly. I use 15 lb Yozuri on my Curado DC's and it works great for me. Should you choose to focus more on jigs & soft plastics I'm not really sure that the DC feature is necessary. Maybe a regular Curado, or the next step up from that, whatever that is this year. An exception to that rule would be if you're fishing alot of docks. I don't fish reservoirs that have alot of docks, but friends of mine who do love the Curado DC because they say it makes dock skipping easier. I can't really speak to that because I don't fish that way, but it makes some sense to me.
I started fishing bait casters with an old red ambassador and I was terrible with it until I acquired a Shimano with magnetic brakes - a Custom X 2000 which I got in the early 80's. Magnetic brakes made all the difference in control for me.
I learned to throw a bait caster, mostly using over head casts, because that is what most of the literature at the time said to do. Then I saw Jimmy Houston on TV, and his little side arm roll cast made alot of sense to me and was pretty easy for me to learn. As a mostly bank fisherman at the time, I made many side arm flick casts with spinning gear and transferring that skill to bait casting was just a matter of educating my thumb rather than my fore finger.
In hindsight, I think that I would have learned bait casting quicker had I learned how to pitch first. The back lashes wouldn't have been as major for one thing. But at the time, I considered a quarter ounce jig with a pork frog a heavy bait, these days I generally throw a heavier bait.
So I don't know, good luck learning a new skill - use cheap line to start. Be mindful that once you start on this trip to learn bait casters, after you learn one, you'll want to own another one, then more as you gain competence with different baits.
