I will keep an eye on the RES in my pond since I had a very large hatch in 2015, those fish are currently 3"+ and and competing with large numbers of GSH of similar size. Body condition seems to be OK. One interesting note is that I don't see very many snails but it is pretty easy to find snail eggs when I look for them. It has been an interesting year with very few newly hatched fry of anything observed around the pond, last year there were fry eveywhere all summer long.
