Our IG has a 3' shallow end then slopes to an 8' deep end, average depth of 5.5'.

The kids like it, but when we go to my dad's, he has a 4' AG (not sure of diameter) so we can play volleyball, and everyone has a blast. We've tried to replicate this in our pool, and it just doesn't work. If I were installing our pool again, I'd think long and hard about a deep deep end.

I guess the grass is always greener...
