I sorry I have to disagree with you.Ive used this rig on one rod all season,and looking at my records Ive had 39 fish on the rig from approx 1LB to35lb,without mouth dammage to any of them.
A frend stoped useing the rig because of mouth dammage.
The problem is the angler not the rig,as ussual.
I play fish to the net regardless of size,my frend bullies them to the net.
The rig normaly hooks well back and the mechanics of the rig force the point and barb deep into the flesh,if you play the fish theres no problem,if you bully the fish to much,regardless of size the hook will rip out on thin liped fish and empale elsewhere in the mouth.
I have seen the same dammage with every rig when the fish has been hooked deep and bullied.
At the end of the day its up to the angler to use the rig safely,I would not use it in a hit and hold situation.
