If you are set on SKB, I would look at the 2SKB-4119 or the 2SKB-4114A.
I myself have a the Kalispell BC431608 and it has been awesome for travel!
Check out their site, I am not sure there is a better built case with a better warranty. An additional advantage is their cases will hold 2 dozen arrows with the bow and quiver attached!

It's best if you can put your hands on both of them and put your gear in them to see which better fits your needs.
