I don't think you'll be able to certify the rapala scale or the stren 50lb or berkley 50lb scales. That is what I have heard anyway. It's because those scales don't always give consistent weights. Like you might zero it, weigh something that is 10.0lbs and it would show 10.0. The next time you zero and weigh it, it might come up 10.2 or 9.9 or whatever. If you are going to try it, just call IGFA first before you send it to them.

You need to talk to Fish Chris about you carp spot on the Delta. He told a similar story about the restaurant with the giant carp under it, and one heck of a fight that he got into with the lady who owns the restaurant and eventually the sheriff. Lots of fun stuff about easements and property rights and whatnot x(
