Why shortchange yourself? I will say that I don't know where you hunt or at what ranges you shoot but look at it this way:
You're only giving up 2x on the bottom side, but you are gaining 8x on the topside. Even if you don't need the 24x, you can always turn it down, but if you find yourself needing more than 16x you can't turn it up.
To quote Burt Gummer from Tremors: "When you need it & don't have it, you'll sing a different tune.".
