I think there's been a lot of good jig trailer suggestions from others for you to consider.
There have also been MANY jig trailer Topics here at BassResource so spending a few minutes to study them will probably be VERY helpful to you. Important to remember, a good jig trailer is a relative term due to the different waters and different conditions that we're faced with at any given time... So a variety of styles and/or colors are sometime necessary to tweak the bite to it's optimum.
IMO, a great starting point is a Craw imitation. You can leave it long or pinch it down for a more compact presentation if that's the Bite preference. Also we should always be ready to change... In a slow or NO bite situation, keep mixing it up on style, size, color and presentation. EVEN when we're in a good bite, they can be GREAT bites if we tweak them correctly.
Main thing is keep it FUN and Fish Safe!
