At almost a year into the pipe, I'm scattered about, primarily functional factory pipes. I'm still grabbing new shapes and brands that I don't have, leaving no stone unturned, as far as my meager pipe budget will carry me.
Looking over my working stock, I see about 15 pipes.
New: BriarWorks Poker, Viking Classic Dublin, Falcon Meer lined bowl, Big Ben Dublin Churchwarden (occasional plaything), generic German basket pipe from P&C, Stanwell 86 Bent Pot, Stanwell 185
Estate: Todd Harris Morta Panel Lovat (My one "artisan"), Dunhill 90 Poker, Pre-Savinelli Rossi Squashed Tomato (aka "The Thing"), Savinelli 111KS Billiard, Savinelli 606KS Bent Billiard, Baraccini Apple (the "beater pipe"), Kaywoodie Carburetor "Slim" Billiard (the "Lakeland Burner")
With the exception of the Falcon, all are used and enjoyed regularly.
In the "strategic reserve" box are maybe that many more pipes that I've not yet tried, a mix of new and estates from as many shapes and makers as I stumble across. Stuff to look forward to some day, I guess, just like all the yet untried blends in the cellar.
So, that's the long winded answer, to say I have no brand. My secret to enjoying them all is to know before hand that each will be unique and require me to adapt my technique and tobacco to suit. If I tried to smoke them all the same way, I'd surely be disappointed with some. I don't ride my scooter the way I ride my big cruiser and I don't try to smoke my tiny poker the way I smoke my huge billiard.
