Kindfisher has/had the same issues I have/had which are unacceptable but not sure the culprit.
Same mouth damage but using size 8 krank micro barbed hooks on a Ronnie type hook on a 5 inch stiff 25lb boom but with an inline 19g guru lead. SOOO not the hook link (too thick) not the lead (too light) not the rod 2.25 12ft Powermesh (too light and through action). Two 12mm bottom baits (match the hatch) bollies on micro hook swivel over a bed of pellet and bollies.
Almost no hook pulls but unacceptable mouth damage mainly in scissors (very few bottom lip holds).
So what the heck is causing the damage???
