I've been through this a few times myself. Bill's observation is a valuable one cause they used the same certified scale 45 min. apart....so there is your answer!
I had to make the decision to run or fish several times this past season. Every time, I decided to keep fishing. The fish loose weight over the first couple hours...then they level out. They don't just continue to shrink. We had a king we weighed for the summer derby that was 29.7 on the scale a few hours after we caught it. We then took it to another tourney we fished that day for weigh in and then returned it to the loc station to hand it over. It again weighed the same 29.7 (1.5hrs later) We had two this season that were close to being top 20, but didn't bother entering them. With the price of gas, It's not worth it for $25 and that's really something that needs improvement on in the loc. If it's not going to make at least top 10, I won't even bother.
There are a lot of factors for your team to consider when deciding to stop fishing and run in to have one weighed. First off, The prize structure in the loc doesn't make it worth while unless your in the top 3-4. For the summer loc, if it won't make top two, forget about it. You can determine that with a good scale and a phone call on the boat. If it might be close to the top few...GO! If not, enjoy the fishing and weigh it when you get in. If it won't make any difference in the $$ placement,why not continue to enjoy the reason your out there in the first place....to fish!!
Just my .02, and congrats on the nice fish!
