I personally do not see why folks have such a hard time telling them apart...fished with Polar this weekend and we were catching a lot of short hybrids and big sandies but could tell before even lifting them out of the water they were hybrids and not sandies. We did not have any fish we would have to ID from the tooth patch was obvious by the stripes and even the way the fish fought to be honest. We were catch and releasing everything anyway but you better be able to tell the difference if you are keeping fish or run the risk of some very large fines as it should be.
