I don't know if anyone ever does this. I know it's the "wrong way" to do things but I have used a spinning reel on my casting rod for a long time.. I love spinning reels I use them almost always, I have owned this particular casting rod for quite a while, my grandpa owned it and gave it to me. Over the years ( before I knew a diffrence in rods ) my spinner has ended up on it. I've known it's wrong but never changed it. It has always worked well, no problems when catching fish. I like the trigger on the rod also.. Would like to see some input on this topic.
