i have a Greenmountain barrel on mine and am very pleased with the results although you did not ask about that brand. if competitive shooting is in the picture then best spend the money it takes to get the best. at which point you may want to throw Lija into the mix.
woodson if i had the extra cash i would offer to buy that single stage off you. i have shot two stages before on other guns along with single stage and for me i prefer the single but again it's what i grew up shooting the most.
