vamike, I'm glad to know it is working out well for you! Ya gotta be careful with the stems, some of them are too tight. A little wax will fix that problem straight up, and you can probably just include some replacement stems with your next order. The standard replacement stems run about 80 cents each. Just make sure you get the right kind, I think the Pony takes the non-filtered ones.
I'm still waiting on my Roley to ship, but I hope to have it and review it within a week. I'm hoping it surprises me and is a good smoke. It just seems like such a great shape to be able to carry it in a pocket.
