I haven’t noticed an increase in hookpulls using sharpened hooks to be honest mate, I wasn’t out and out snag fishing admittedly, but I was hitting and holding to stop carp kiting into a corner (which made landing them more tricky) on the take and if anything, a touched up hook increased my hooking ratio, I only had one hook pull out of 20+ fish and that was a single figured fish trailing a large branch it picked up on the way in, I was destined to lose that fish regardless of whether the hook was sharp or not I think, a branch attached to the hooklink isn’t helpful! I thought I was into a monster until it surfaced! 🙄
