Longrifle or Hawkins?
The longer barrel of the longrifle gives you a longer sight radius for more precise aiming.
However, its been found (Wallace Gusler told me this and that the Germans got it right the first time with their jager rifle) that 32" was about the most effective barrel length for a smokepole. Hence the extra length of the longrifle really wasn't all that practical. So, I would lead toward a shorter 32 inch barrel gun over a longrifle. It would be handier in the woods and less prone to breakage (because it is thicker).
