I bought one this year and I love it. It telegraghs strikes really well and fighting fish with it is fun. It is a bit soft for flatlining. I have a 7' Vances tackle.
I've spiral wrapped all my trolling rods for years. The real plus is the spiral keeps the line from rubbing the blank, with fewer guides than a conventional wrap. this saves on weight and is less work to build.
Monday my 2 rainshadow RDR76L blanks showed up. I will be spiral wrapping with micro-guides. The action on these light blanks is EXACTLY what I was looking for. I'm only sad that I will have them ready so many months before kokanee catching gets good. Anyway, the theory is that spiral wrapping makes a more stable rod.
