Chris. I agree with Horizontal Hunter in trying the two different stocks for Excal. The thumbhole stock is an inch shorter and I didn't like the feel of it for that reason as it just didn't seem to fit right for me. I own their Vixen 150 & Exocet 200 and their stocks are the same as a rifle stock and they fit me a whole lot better.I'm not sure why they made the thumbhole stock shorter but I guess they had a reason for it.
