I have a Hog Hunter on the way that is going to be going into a XLR Chassis system but I would also like to buy a Boyds thumbhole stock for it but I am not sure if I should get the stock for the Standard barrel or the bull barrel. I know down the road I will end up buying a bull barrel but for now I wonder if the bull barrel channel on the Boyds stock will look funny with the standard contour Hog Hunter barrel in it?

Also will I need a metal trigger guard right off the bat to work in this stock?
