How ironic, I came here today to post the very same request (user option to select fish size), looks like you beat me to it Taxman.
Anyway, count me in as one of the people that would like to see this feature implimented. A shame that you would have to limit it to downsizing the fish only and would not allow for even a slight incread in fish size, but I understand your reason for not wanting to do it Jim. Still, having the option to downsize is better than none!
