This was no cross we caught,it was pure largie. at Yatesville lake you will catch largies with a tooth patch and that lake does not have a lot of spotted bass. It could be teh cross with nothern and southern strains that cause this, as a lot of our fish are crossed together now. Yes those mean mouths are in lake Cumberland, saw two weighed in this year in different tourneys, also caught a small one myself, they are cross with smallie and spot, they spawn around the same time and around the same depth as smallies, so crossing can and is happeing.
