In a carbon, a Terminator Select from Carbon Express in size 45/60 w/a 125 grain point should do quite well.

That or a Beman Pultruded Carbon; click here. Using a good drop-away w/ the outserts and G-nock adapter will give you a very good penetrating shaft. Along the same line the ST AXIS in size 500.

W/ a good sharp cut to the tip like a Steel Force, Phantom or RazorBack, she should be good to go.
