I been quite lucky this year and only had three badly hooked fish which I had to keep, two were Pannies and one was a trout. I almost never get Rig badly hooked, nearly always nicely in the jaw. I put that down to my choice of hook, but I suppose Rig might chew their food before swallowing. The occasional small school shark or dogfish also get gill hooked so I normally turn them into crab bait.
With regards to Snapper I think I blanked three out of the five trips I done (unless I catch a Snapper or something equally exciting I consider it a blank) . With only one fish over 10lb being caught. The fact that I only done 5 trips is a bit disappointing Been spending to much time trolling.
