If we're talking about C&R, I just think they are a real bad idea for any trout or any fish for that matter...no matter what size. Like mentioned previously, picking up a big fish out of the water by the jaw can't be good for the fish if you intend to put it back. I don't need to know how much it weighs. I do like that low cost fish grabber that was posted. I wish I had one for the big pike I had on my line while I was sitting in the float tube in Michigan, thinking OK...NOW WHAT ???. He was looking at me, really P Oed...and all I could see was a mouth full of teeth I didn't want to have anything to do with. It was then and only then that I said I wished I had one of those grip things...only to keep head control while I tried to get the hook out...and NOT to pick the fish up with. In this case...the fish ended up wearing lip jewelry back to his ambush spot.
