I've only smoked Irish Oak in my new Peterson Aran 150 and after about 12-14 smokes in it I'm really starting to taste a sweetness in the blend that was only slightly noticed every now and then in any pipe that I had previously smoked it in. I'm not sure if I'll keep this pipe just for VaPer blends or not yet; but I must say that it is a really nice smoke without the hindrance of other blends showing muting the taste of the one being smoked at the moment. After how long it took to break in my last Peterson pipe I decided to coat the bowl in honey and let it dry before I smoked out of it and the break-in process definitely seems to be happening faster, but the first few smokes were definitely hotter than without the honey in the bowl and had a taste imparted by the honey, the cake build up seems to have definitely accelerated without being too quick in my opinion. I'll see how this cake build up holds up over time before making a decision either way as to whether I'll use honey again or not; but if it holds up and the break in on the Peterson proves to be properly I don't see why I wouldn't use it on every new Peterson I buy in the future.As per usual with everything pipe related YMMV
