I know Gibson and Barnes are willing to alter things quite a bit. Their flight satin lining is pretty nice and heavier, though I have never couple it with their goatskin to date. Their goatskin is very nice, though I prefer their russet vegetable tanned goat over the other colors which are chrome tanned and though soft, just seem thinner to me on feel. I know there is a $38 charge for changing things on a jacket, and then the price changes based on what you add or take away. For example, changing something to horsehide from goatskin added about $50 to the price from what I remember. I hope that helps.
