Hickory wood is great for most meats, and game.  It has a strong, very desirable flavor profile.  It is exceptionally hard, and burns long and very hot.
 
How many uses will you get from one box?
For a heavy smoke flavor, a small box may give you 2 - 4 uses/meals. If you prefer just an essence of flavor, then a small box could last possibly up to 7 - 8 uses/meals.  The more wood that is used, the more intense the flavor.
A large box will last about 20 uses/meals.
