Corey,
I would suggest to get the best yields, use double shoulders or bends for belts up to 55" and buy a back when you need extra length, and you don't have to worry about the belly area.
My name is Roger Folmar of RJF Leather Co., I carry high grade veg leather in all weights including Double sholders, bends, backs, sides. Check out the web site for other leathers.
Thanks, Roger
