quite simply, better resolution and therefore nicer looking dynamite!
I have done three versions.
one has tape binding (shamelessly nicked from the snakes's stick grenade skin)
one has the original steel binding.
and for realism freaks, one ditches the red and is in a basic greeny/brown paper wrapping as it would actually have been. (see here: http://www.shockmansion.com/wp-content/uploads//2010/09/tn_Inert-German-Dynamite-bundle-7123-120.jpg?9d7bd4)
