Thanks Bill.
I question my ability to measure the gape accurately. Been using some plastic calipers which I find much easier to use than a tape measure, but like you said, how much does one open the mouth. I try to do like you, open it to the point I think the fish could do with muscles to swallow a fish without stretching.
At any rate I guess I have joined JHAP's GSF club because have started returning to the old pond any GSF that looks good that is above 6.5" and culling everything below.
Guess I'm going after trophy GSF.
