Castro,
Here's a couple Loomis' I came across. They're both 12 ft. Couldn't find anything longer. Whadda want with these ultra long rods anyway??? Tullie dippin or what??? STR1445C and SUR1448C are the models. The first one is salmon and the second is surf. Don't know where you could get the blanks, but you could probably con some tackle store into ordering one for ya. I'll let ya know if I find anything else.
