Re: Time to get a new one!
So, neither of them have engraving which throws the subject of aesthetics out of play. You can't decide on the MZ which has a good reputation or the Pyramid which doesn't really have much of a reputation yet, as far as you know. Have you checked for reviews on either of them? Perhaps that could tip the scales one way or the other for you. As, I believe, uglybiker said, the Pyramid may have a slightly more restriced draw and be shorter than the MZ. If either of those aspects matter to you it might just make the choice for you then. Smoke happy.
