I have had the chance quite a bit over the years to do just that back in some of the canyons.I take the hooks off my spoons and such.I even got to fish diferant corkies infront of a summer run once.Just didn't set the hook and changed presentations.Alot of fun to watch a fish take your stuff and then spit it back out all in its own time.Verry educational.Helped me learn not to strike to early when sight fishing too.I love bringing new guys back into a canyon.They always strike right before the fish bites.
