Probably just personal preference on that. Remember your boulder will most likely be level with your patio and not sunk into the hole that is there now. Typically taller rocks would have more splash, more sound. But there are ways of getting the sound out of shorter ones too. Lot of factors that go into it but honestly I think it boils down to what you want to look at everyday.
