hey phil, its the barbless hooks that do the damage IMO as they can and do come free then rehook rattle about and do all sorts when the fish is acrobating about. whereas a micro barb will catch and hold every time, if you use a pattern that will catch in the bottom of the lip (such as the gardner mugga) then you minimize the damage to a single puncture in the meatiest part. you can always cut the hook free with side cutters by pushing it all the way thru then clipping off behind the barb, the hook will then slide easily away. a quick dab of carp treatment and she can go back feeling like shes had a day at the spa
as i said before IMO, this will be disputed by others i dare say
