RE: good or bad idea?¿
Exactly, Il Bow Man. I was about to say the same thing. The drag handles the breaking point of the line, while the brake controls how free the spool spins upon casting.
Someone can correct me if I' m wrong on this, as I realize techniques change over the years, but when I bought my first baitcaster -- an Abu-Garcia with one of the first " thumbars" -- the owner' s manual suggested holding the rod out horizontal with the lure you were going to use, releasing the spool, and adjusting the brake until the lure slowly fell to the ground. The ideal setting was for the lure to settle to the ground without producing any " overspooling" ; in other words, when the lure hit the ground, the spool stopped turning.
Keeping this rule of thumb in mind, you can adjust your baitcaster to any lure. Of course, you' ll still have to " thumb down" your casts and feather them to a stop.
