I have but not a fan, Id rather use cut, more blood, etc. Also when I cut the heads I toss the body of the gill in the lake close to the bank to see if that helps with attracting them, not sure if it does but I do it. I hate to bobber fish, its annoying to get up and recast the bait cuz the bobber came in or floated somewhere its not supposed to be. Id rather toss some cut bait and leave it there in one spot for an hour or so, then if nothing, rebait and cast it again. Seems to works so far for me
