Snubbers are good to start out with when using braid or wire, not necessary with mono for the stretch. Once you get the hang of setting your drag with the wire or braid and you have a good rod designed for dipsy work, one that has a forgiving top end and a sturdy back end, you can delete the snubber. I have used snubbers before (but not anymore) and I can say the 8 inch is best for wire and braid. It is important to make sure you have the leader to the lure be matched to the length of your rod and even a little longer, to be able to net a fish with the dipsy at the tip of the rod. Keeping the leader long enough to place the dipsy farther away from the fighting fish also has less leverage for the fish to wrench lose from the weight of the diver, thereby reducing the need for the snubber as well.
Drag set just so a tick or two goes out once in awhile at your troll speed and the use of long limber tip diver rods will give you an advantage in hook up over using the snubber, in my opinion.
