No need for 2" width 1 3/4 is more than enough even for whitewood bows at 100# (IMO)
Depends what you mean by close shooting.
As Mikkolaht says, with a sensible arrow you should be ok at 10 yards.
Some warbow arrows are, in an attempt to be authentic, too stiff.

PS. Mind it's some time since I could pull 100
