The Royal Safari is one of Ferguson's bows that Bear is producing under their agreement. Another is the Patriot. I got to handle a Patriot at Cabelas last week and really liked the feel of that grip.
But when I read the words 'Bear longbow' and 'boxie' in the same sentence, I'm with Chad. That screams "MONTANA". It's like gripping a bow made from a 2X4. After shooting it awhile, I did find that putting the edge of that box into the crease of your hand helped produce a very repeatable grip. That grip is not something I could come to actually like, but I was able to find a benefit to it. I could live with it, if I had to.
But you know, if all else fails, that's what they make wood rasps and sandpaper for.
