A little spice as in a little more variety than just your run of the mill bass/bluegill pond... 15 acres is a lot more room to work with and makes managing more than 1 or 2 predator species a little easier. So if you wanted to try something different than just LMB you could also consider HSB, WE or YP... Plus I think the potential to grow a trophy fish is a little more reasonable than say in a 1 acre pond. IMO
