I hate noodle rods worse than cold feet, so I may be biased though.
Not trying to sound like a dick.. but you just have never fished with a top quality noodle. They are just as sensitive as a spring and strong enough to fight big fish. I caught a measured 1.75" bluegill the other day that moved the tip pretty good. And I've caught crappie that raised the tip. All with 3mm tungsten wolframs. Here is a video of the rod I use, you may have seen them at the ice show. http://www.youtube.com/watch?v=11PrRqVkTWA
I finally got out with my st. Croix legend today. I dont feel rod is $50 quality, but the idea/design is. The spring bobber is a nice design, and being adjustable for different weight jigs is just awesome. I found a setup that works great for me.
Sell the rod and make your own st. croix tips to add to your favorite rod. Cost is about $2 each plus the actual springs. There is a topic on here that shows how to make the tip, and there is another on here that shows how to make your own st. croix springs.
