Yes, I'll typically use a limerick type hook (large eye) and slip it over the baits hook. I'll uses a piece of surgical tube threaded onto the baits hook after installation to hold the trailer in place.

I put the buzzbait on a swivel and hook a shortened size 2 snell hook on the swivel. works well for me

yeah i would put one on. you dont miss near as many hits.

I have used trailers on buzzbaits in the same manner that Beekeeper described and had good results. Another tactic that has worked well for me over the years is to slow my retrieve down when the fish are striking short. Also,many times if a fish hits short,don't give up,continue to reel the bait in a bit slower and don't set the hook when you hear/see the strike. Wait a split second until you can feel resistance,then set the hook. Hope this helps,good luck.
