OK. I had that thought after our Saturday shoot. I had a few people try this gun to get their opinion. One shorter shooter thought it was a bit long for their size.
After that, I thought of a shorter version, stock length, or like you mentioned, adjustable. That will take some designing, which is not a big deal. My plan at the moment is to see if I can duplicate the current stock and go from there. At the shoot I received some good feedback. Everyone liked the look and feel. At least I'm on the right track.
I'm thinking about different woods, as I have an amazing exotic woods supplier locally. Exotic wood isn't cheap. I'd like to perfect the current wood ply version before attempting an exotic wood version. This is down the road. I don't want to get ahead of myself until I have a few birch ply duplicated samples made to my liking.
In order to gauge stock fit, it looks like I may need to buy a few SVT's for the receivers. This would allow me to quality check for fit. Someone hiding a big pile of SVT's here in Ontario? The supply seems a bit thin right now. Only a few dealers have them in stock, all out west

. I wish a local-ish dealer had a few to avoid the cost of shipping, besides I'd like to look at what I'm getting. I wouldn't use a collector grade for this purpose.
Thanks for the input everyone.
