I'm not sure what you mean by "that big wadge of sail hitting the top of the snuffer," but one tip I picked up somewhere on the net is to tie a stopper knot in your downhaul line about 3 feet or sow below the top attachment point. That keeps the attachment points along the spinnaker from bunching up when you are trying to haul the kite into the snuffer so that it goes in more smooth and fast so I can keep up with the dropping head.

I sail single handed too and this helps me tremendously. Maybe it will help you too.
