I dunno about all this, but in my mind the jpxi would supercede some of the others due to the stainless frets. I guess it's a personal preference, but a guitar that wears less has greater value. I'm not sure of the demand, but sure would love to see the stallion continue with the stainless... It would be interesting to know whether jp's a big fan of the stainless. I believe jpxi is the only jp model with them
