For me savory is great for eating but in terms of getting messy in, does nothing. To each his own of course, and I appreciate all different substances used for various WAM productions. When I think savory, the top 3 food items comes to mind: baked beans, spaghetti/spaghetti-o's, and certain condiments.
Messygirl have done some great scenes and as mentioned before so have Ariel and Jayce. Model to look for who takes a great Savory wamming is Vika who takes and gives out a massive amount.
MostWam do some great ones as well.
So in conclusion. Yes all of the above.
Do you prefer American or English Savoury? I notice American producers seem to use quite a lot more condiments than us Brits can get our hands on easily.
