Try asking at http://www.rodguild.com/. Those guys know their stuff. It really looks like Lamiglas numbers on the blank and they make a lot of blanks similar to that. Wonder if the person you contacted checked their discontinued blank numbers.

Consider how you fish a rod when you're throwing plastics. If you point the rod below or to the side of the direction the line is going to the lure, I'd agree about the roller guides. However, if you generally fish with the rod pointing above the line (like you probably would from a float tube) then the roller guides should be fine. You just don't want the line rubbing on the frame all the time instead of rolling along the pulleys.

Good luck with the rod building.
