In some situations a scope may be to the advantage. If still hunting were open area is prevalent. ( near a swampy or grassy area, on a ridge or tree stand that may allow for open pockets).      

                    Open sights on a rifle or a shot gun is aways a good bet. The terrain is very rugged and you will be hunting in the bush. Line of sight can be resricted and your view obscured. Muzzle loaders with open sight as well as bow hunting can be a good choice.
