I never knew this till the other day. You can get custom rod tubes from Clear Creek. Since I am going to France and I need a tube for all of the rods that I am going to bring. I found out that Clear Creek can make them to meet whatever size you need. I got one that was 34 inches for the 11 foot 3 and 4 four weight rods. You can even get your name on it! It's a six inch diameter tube that can fit 10 rods!! Check out the photos and head to your local fly shop and order one up!
