When I draw traditionally I like to have really thick lines! My favourite lineart tools are Gelly Roll 08s, Pilot V Sign pens (high quality liquid ink in those! mmmmm), ZIG Millenium 08s and Staedtler Triplus felts. Those are the tools I recommend for anyone else who likes thick bold outlines. (action artists for example)
I like to do my sketches in coloured pencil since they don't smudge too easily. No real preference. Anything from crayola to bic does me fine.
As far as colour goes I'm a stickler for artsy limited colour palettes. I like to colour using Copic alcohol markers and watercolour especially. In my sketchbook though I experiment with anything and everything. I like to pick out a handful of markers and play around. I especially like to do a loose pencil sketch, then go over in marker with colour and do the lineart last. If you like an energetic traditional style with strong intense colours this is the process I recommend.
If I'm stumped on my colour choices I just scan and print a lineart example or sketch onto marker paper (the thin stuff - I use Winsor + Newton brand) and just experiment until I find a palette I like. It's all trial and error. Soemtimes I end up with more than one nice looking draft and I keep several of them just so I can use the palettes later.
I'm also a bit of a stickler for doing my rough concept sketches using ballpoint pens. I try not to do it that much but it's just really relaxing to draw with a ballpoint.
As far as brush pens go it's the Pentel pocket brush pen for me. All day every day. I fill mine with brown ink and use it to create sketched portraits. Sometimes I pair it with a black liner or a red ballpoint, I dunno. I love to play around with it.
That's my ramble on traditional art supplies! blegh. I'm chaotic and own a variety of strange art stuff.
