Peter,

For fingerstyle, I think you'll find the majority of players gravitate towards Orchestra models, 'L-body' models for Larrivee, Grand Concert models from Taylor, etc.

These are smaller bodied guitars, or at least have smaller waists than Dreadnaughts. But, please try all types out before you make a decision.

Regarding brand - I wouldn't pay much attention to this at first. Get something that feels comfortable first, then pick a brand.
