Do I need a loop knot?
A loop knot (non-slip loop or Rapala) or a small snap gives the bait a free hinge so it hunts side to side on the twitch. A Palomar tied straight to the eye stiffens the action a little — fine for a hard rip, wrong for slow twitch. Snaps also let you change colours in seconds; use the smallest that fits.
