HeY Eric, Nice to hear from you again!!
I have added a few smaller YP last fall and this spring from other sources. Thus I know a few 3 inchers, Everything I have pulled out on my own is between 12 and 16" Some real big lunkers over the past 6 years!!
The SMB I saw one or two last year that made it to about a 4 inch size but nothing lately. I think because of the amount of SMB and YP that are larger I have lost most of the new YOY type fish.
I have ried Goldens in the past and they tend not to handle the thermal shock or new conditions very well when adding themin. I let them adapt to the temp while in their bags/containers but still seem to lose them soon after. I did see one Golden about 1 or 2 years ago that got to be about 10" bu have not seen him lately.
