Well looks are deceiving biggest taped fish this week was 41 by 21 but my guess was that fish was only 20 # and I usual can tell with in a # of actual weight without measuring correctly! While another fish was39 by 19.5 that was deep all the way through that I know was heavier maybe 23 or 24# I know we have formulas for weight standards but fish in different stages of their cycle have a weight difference a big dark buck compared to a chromer may vary as much as 3 or 4 pounds but all and all that is a nice fish no arguement here!!!
