Anybody do any curved linears?

Looking to do some ceiling curved and wall con-caved/con-vexed linears.What brand do you suggest?
The Shoemaker cores look like they would be a sweet custom finish.
The Krueger 1500's look good too but have the flanges, guess I could do hidden flanges on them too.
Should I just shoot myself now or later?
This should be lots of fun........................pun intended.
Any tips on figuring exact radius's? I have an .xls for this but math is perfect and carpenters aren't.
Any tips on custom boot designs and fabricating...............
