cm2ras, welcome to the forum. I also had trouble with the avatar thing and it took me a while to figure it out. You might want to contact one of the moderators and they can walk you through it.
In regards to all of the different blends out there, it can be very daunting. I would suggest going for a blend in the basic categories. I do not know what you prefer but the way I categorize the blends is like this.
Aromatics...Lane 1Q
English.. GL Pease Caravan
Virginia.. Dunhill Flake
Virginia/ Perique.. Escudo
Virginia/Burley...Mac Baren Old Dark Fired or Solani Silver Flake
OTC's mostly straight Burleys with a topping... Carter Hall
I think this will give you a pretty good representation for the different categories and there are a few flake tobaccos in their which I suggest you cube cut for preparing. There are multiple threads about cube cutting and even some videos. I picked these blends based on their availability as they should all be easy to acquire from one vendor. I recommend using one of these three sponsors. Pipesandcigars.com, smokingpipes.com and 4noggins.com. Put all of the blends in the cart for each vendor and see who comes out with the lowest price. I use all three and if you purchase over 100.00 shipping is free from all these guys, remember to buy plenty of pipe cleaners. I prefer the BJ Long extra fluffy tapered and bristled for most of my pipes, but some of mine need the thinner ones so grab some of the thinner BJ Longs. If you have pipes with vulcanite stems, Obidisian stem oil has been great for me in keeping my stems free of oxidization. Hope this helps and do not be afraid to ask questions, it is what we are here for.
