Finally I have found some! Golf club tubes that is. Several months ago some one mentioned that they were ideal for storing the upper part of your rod while trippin. I have been keeping my eyes open and have come across them at Dicks sporting goods for $1.79 each.

I concur and think they are absolutely perfect for the unintended use of rod storage/protection. About 30" long and very light without being flimsy. Just about perfect in diameter they should work with most rods.

I have been kicking around various methods of securing the tubes and think I might have hit on the ideal solution. I believe some industrial velcro would work fine and dandy. I have used this stuff before and it is quite sticky to most surfaces. I think it is some 3 or 4 inches wide and about a yard long. Cut to fit. Light and able to flex with the boat it should be ideal IMO.
