I was looking at the avg size chart of healthy bass and the difference in weight between a 14 inch and a 18 inch bass is more than double....that alone is impressive. So, I don't remember what I read on this forum, but it certainly seems possible that an 18 incher could hammer a 14 inch bass, but certainly could easily handle anything smaller.
I'm wondering just how many of my million 12inch bass get grief from their bigger buds.
