I'd sell (in this order):
1) L. Kansas. I never understood the hype over this bag...but the color is pretty!
2) Silverado. If you are going to own a Silverado it should be python...

.
3) Rose City (especially since you said you only needed one)
4) Sable Paddy...it's a very very very rare color. In time you'll be able to sell it for more than it is worth now.
HTH!
