WOW, never thought I would find so many folks in one spot that agree with me on this!!!!!!! I want to get one thing straight , it is my feeling that you may need a trailer hook if your using some run of the mill spinnerbait and I wont mention names[i may use them as sponsers,lol] but when you use a hand made bait [ and I use celticavs] you darn sure should not, unless your just starting out! That brings me to when I may use one , 1. open water schooling fish, 2. high speed burning retrieve, and when fishing buzzbaits. The most important thing to me is being able to throw a spinner bait into cover, and a trailer hook is out! I fish spinnerbaits for fish that are tight to cover or feeding off the bottom around scatterd cover. As Celticav knows I'll drag a spinnerbait through some stuff that most people wouldnt and a trailer hook is a no no. My favorite technique is slow rollin and I mean slow, real slow. If its there my baits going in it [boy am I glad I know where to get more]. Some people fish these baits in differnt ways then I do and thats what works for them and is fine. Everyone needs to have there own style anyway, but for me I'll keep the trailer hooks in my tackle bag. DANO
