Welcome George,
Good start with MM Cobs, but also a good/solid briar would not hurt as well, there is a deal at pipesandcigars.com right now on Stanwell Brushed Brown Pipes ( follow this link http://www.pipesandcigars.com/limitedgift ) , I would snag at least one for only $19.99 - then test the waters with bacci and that line up of pipes to see if you want to stick with it.
Now for the wonderful world of pipe tobacco blends; hard to suggest what "You" will like , but I can list a few diff blends that you may want to try; visit tobaccoreviews.com and look at the reviews there, will help as well
smokingpipes.com or pipesandcigars.com are great places to shop
Blends;
Dunhill Flake
Dunhill Flake is a medium strength flake of selected grades of Lemon and Bronze Virginias. One of Dunhill`s most expert blends of highest quality.
Peterson University Flake
Mahogany, Burley, and Kentucky are blended to create a unique pipe tobacco, Peterson's University Flake.
Mac Baren: HH Old Dark Fired
A bold flake of dark-fired burleys in a well balanced unity with flue-cured Virginias. Mac Baren's HH Old Dark Flake is hot pressed, meaning that during the pressing, heat is added by steam to the tobaccos which causes the tobacco to intensify the marrying process giving us a bolder tobacco. The robust, earthly flavor of the dark-fired Burleys shines through in the taste, and you will experience a deeply satisfying smoke indeed.
A & C Petersen: Escudo Navy Deluxe
This old classic, Escudo Navy Deluxe, is a popular Perique/Va. curly cut tobacco in large coin size.
Cornell & Diehl: Night Train
or C&D's Night Train, bright Virginia ribbon, bright Virginia flake, Cavendish cut, Virginia grown brown Burley, and Perique are pressed into an old-fashioned crumble cake.
Cornell & Diehl: Morning Drive
The mixture of red and bright Virginias comes together in perfect harmony with just the right measure of Burley, Turkish, Perique, and Latakia.
G.L. Pease Jackknife Plug
For Pease's Jackknife Plug, dark-fired Kentucky Leaf and ripe red Virginia tobaccos, with their deep, earthy flavors, are layered on a central core of golden flue-cured for a hint of bright sweetness, then pressed and matured in cakes, and finally cut into 2oz blocks. Slice it thick and rub it out for a ribbon cut, thin for a shag, or chop it into cubes.
G.L. Pease Temple Bar
Rich, ripe red and sweet golden Virginia tobaccos are generously spiced with fine, fragrant Orientals and enhanced with a delicate touch of Perique for a bit of added depth and complexity. The leaf is carefully layered and pressed for a fortnight into large cakes, which are then cut into bars and tinned, ready to be sliced and rubbed out as desired.
Boswell Blends can be purchased in smaller amounts, they have great aromatic blends, so check out their site as well
