Not really except stay small. I use a snap swivel and for UL go with the smallest I can find which is darned small and still several times stronger than 4 pound test. People have a preference for styles but to me they all work about as well. Some people absolutely refuse to use a snap. For spinners I believe they tie on a small swivel, a length of leader, and tie onto that. Check the terminal tackle pages at
Bass Pro or
Cabela's for an idea on styles/sizes.
If you're boating an old trick to untwist a line is to use a heavy plug (and a swivel) and let out a lot of line while motoring at a good clip. Not perfect but gets most of the twists out.
