Today, I picked up a couple pouches of OTC Prince Albert & Carter hall for roughly the price of one pack of cigarettes. Seemed like a deal and a way to relax my palate for a couple of weeks been smoking light English solid for a month. Taste buds need a break. Here comes the assistance question. Those more familiar with Kaywoodie's may know. What's the difference between the super grain & flame grain pipes? I have read that super grains are highly collectible if they are older. In a mood to purchase one to add to my modest collection of puffers.
