Definitely pick yourself up a Peterson if you don't have one. It's worth it to at least see what all the hooplah is about. I currently have three (Rock of Cashel 408, Donegal 106 and Emerald 87) with another in the mail (Donegal 80s) and hopefully another for Christmas :lol: . To say I have the beginnings of Peterson PAD is an understatement. They all stay relatively cool to the touch throughout the smoke and have draws that I find are right in my "sweet spot".
As far as Petersons as a whole, the shapes, finishes, and price point just work for me. I find when I start looking at pipes from other makers, I'm just not compelled to make the purchase.
My only issue is with my Rock of Cashel 408. The fit of the shank, brass band, and stem doesn't streamline very well. Granted, the RoC line is (from what i've found) the second cheapest line on offer. Still, for ~$60 you'd still expect a little better fit and finish. Of course this is just one pipe, your mileage may vary.
My current favorite is my Emerald 87. The bowl is on the small-side, which i've found is excellent for flakes and higher nic blends.
