Scotty rod holders and transport question

[Trout_lover]

I guess deflating it makes more sense when I have a telescope in the back. I was worried about restricting my vision when driving. I went to the Cabelas website and looked at the triple plastic rod holder for about $20. Where do you buy the thin nylon cord that attaches to the 2 "D" rings on the storage bags? Also, what length of nylon cord should I get? I have a Caddis Navigator II float tube that I need to start using. Shore fishing can be expensive when I an using lures.
