Absolutely not, once a circle is in the corner it ain't coming out easily even with a squashed barb, I've had to leave a few circle's in some fish due to it taking too long to get them out and having to quickly get the shark back safely into the water. By the way wade you interested in getting some 287lb carbon coated stainless steel wire? I'm ordering a 200m spool of the stuff and it works out to R300, same stuff Don and co use.Oh yes, forgot to put this in the post, does squashing the barbs on a circle effect the catch rate? do you lose more fish?????
