+1 for the Iron Wills (125gr solids), though not the single bevel you mentioned. Started toying with some 125gr Cutthroats at the end of last season, but can't tell you any positives other than the head will pass through my targets! Last 3 deer I have shot have all died within 30yds... love it when they don't know they are poked, walk away, and tip over... used to shoot the flappers and while they work, don't have them bounding off to the next county like they were smacked on the a$%... much easier to track deer when you can see them tip from your saddle. As for sharpening, I have a Stay Sharp jig that works well, a DMT diafold I keep in my bag should I need to sharpen broadhead/blades for any reason in the field, and a double sided waterstone at home for sharpening by hand. Takes some practice, but once you have the bevel angles figured out, not too bad.
