I have a 311KS in Red Gator which is used for VaPers and one in Green Gator that is used for Latakia blends. The red is used while I am on the water in my kayak paddling the marshes of Louisiana, filled with Bayou Morning ribbon cut or Mac Baren Pure Virginia. The green is for later that evening and is often filled with Peretti Tashkent or GLP Quiet Nights. The real gators don't mistake the red one for one of their kin, so I use that one on the water. This way, I don't raise their ire while in their midst. A safety measure!
