Closing the bail by hand on open face reels is one of the best methods to avoid line twists and resulting bird nests.
If your line is already twisted or has taken a "set" or "curl" from being on the reel all winter long, simply let it spool out behind your boat ( at low speed ) with nothing on the line and drag it a ways, you'll be amazed at the drag the water puts on it, and retrieve back onto the reel. This accomplishes two things: first it painlessly takes all the twists out of the line and, second, the immersion in the water wets the line and allows it to "relax" and lose the set most lines develop over time.
Remember ! Practice catch and release.....It'll grow on you...
