Yes, they grow faster. Typically not by much, because most lakes are overstocked. If you took two barren lakes with an established aquatic food base and put the same number of AF3N trips in one, and diploids in another, you would notice a difference in growth. Problem being, noone has done this on the ground, and I hope they do soon. There's going to be 30 or so lakes like Silkstone and Lovett created near Coal Valley in the coming years. Those lakes could be one heck of a playground for seeing what works and what doesn't.....
