Peter- I have never tried the regular spinning leaders that you speak of. I do suspect that they would be a turn off to other species. As far as hard mono, it's good to hear that you haven't had any bite throughs, but the thought of leader replacement after every fish isn't too appealing.
Don't want much, do I?
Sean- Braided line just plain sucks for fish with sharp teeth. I think it gives them even more leverage for the bite through. But you're thinking outside the box, and I like that.
Anyone else? Frenchcreek?
