I agree that baitcasters are hard to use at first and you have to make sure it is adjusted correctly for the size lure you have tied on. If you haven’t already, check the instructions that came with it to see how to adjust so it doesn’t overwind or backlash. Here is a simple rule of thumb: push the button and let the lure start to spool off line and drop toward the floor. If it doesn’t drop when you push the button, loosen the nut that controls the tension (not the same as the drag) until it starts to drop slowing but steadily. If it drops quickly and hits the floor and a bunch of lines keeps spooling off (backlash), then tighten down that nut a little to slow the drop. At that point the reel is set as well as it can be.
The other thing that can cause problems when you are new to baitcasting is putting too much wrist into the cast that whips the tip like you do with a spinning rod. I have less trouble with I use a slower whole arm type movement and not as much wrist.
I also have the Shimanno Curado and really like it, but I also have an old Shimanno Bantam that gets a lot of use.
How some of this helps.
