I've never done it but always fancied it. I am just not sure if it is cruel or not? So we would only be fresh water fishing, anything we catch will be thrown back. DP says that because the hook is so sharp it doesn't damage he fishes' mouth but i can't see that it doesn't hurt? Funnily enough i wouldn't have a problem with sea fishing if i were going to actually eat the fish, but i wouldn't want to damage a fish and then let it go, if that makes sense.
