This is the information you should know.... Centrifugal brakes are designed to prevent the reel from speeding up too fast at the beginning of the cast, and causing a birds nest. The cast control knob is to prevent the spool from over run when the lure hits the water.
You CAN use 1,2, or 3 brakes and doubt you will notice any wobble during the cast. It takes someone very proficient with casting reels to notice a difference. If I were you I would set three to start, and go from there.
First thing to do is set the cast control knob. Step 1 with all brakes OFF and the cast control knob tightened down. Hold the rod at about eleven O'Clock and disengage the spool, and slowly loosen the cast control knob till the lure begins to fall slowly, but not too slow. Now set three centrifugal (none pitch) brakes to the on position, and you done. This is the correct way to set this reel up when going through the learning curve. If you want a bit more distance, turn off one brake at a time. Hope this helps.
