Any idea what weight Grizzlys you have? You'll need matching weight field points. Feather fletching, of coarse. Many prefer carbons, I prefer wood. Just personal preference...
If you haven't already done so, have someone mark your true draw length on an arrow. Add an inch for broad head clearance. That will give you your "back of point" (BOP) arrow length. (Yes, that extra inch makes a difference!)
Once you get back to us with the info, I'm sure you'll get lots of suggestions to get you started!
