FairChase:
I'm 6'3" and have installed a number of black extensions on the guns I have refinished. They work fine but in my opinion I think the wood ones look much better. I will be putting wood extensions on some in the future. One good source of wood extensions is your local gun smith. There are a lot of guys out there that are vertically challenged and need to have their stocks shortened. I picked up two pieces recently that were cut off stocks for guys that do a lot of trap shooting. Nice walnut of about 1/2" thick.
I would suggest patterning the gun before you put an extension on it. You may find that it shoots just fine the way it is. Once you put an extension on it, your cheek comes down on the stock in a differant position and the point of impact will change. This is very evident if the stock has some cast. At that point you may need to bend the stock.
