Nice work. Here is my opinion, which I offer humbly, as an amateur:
1) I like straight grips better than either of those.
2) I like the one with the bag grip better.
3) I like the raised comb line of the square gripped one you made, but the toe line might better have been brought up. I know this might give a tendency to "goosenecking" at the grip, but the stock looks a little too deep at the butt end.
Once again, nice work though, and thanks so much for posting the good pictures and story.
Best Regards,
Tony Lowe
