Max,
No experience with Goodoien. They're really pricey and he like's them thicker walled than some. He won't make a 7/8" .50 or a 15/16" .54. Given comments from Don Goetz elsewhere on barrel wall thickness, I just don't see that. I just ordered a de Hass target barrel from MBS for less than half what Goodoien gets for his. Personally, given the number of competition records held with Green Mountain barrels, I'd be hard pressed to see a straight-walled barrel being worth that much $$. I just doubt there's that much difference. I'm sure there's someone who'll disagree with me. Also, the big selling point for these seems to be the hand-lapping. Not hard to do yourself.
