So far the only noodles I have used are the ones I made myself by sanding down fiberglass blanks, and the DH Al Dente I bought this year. The Al Dente rod is nice, but I feel the tip is juusssttt on the heavy side for the jigs I usually use (4 mm Tungsten most often). The tip does load very very slightly with a 4 mm jig, and does flex up and down some while jigging, but not a lot. I was actually surprised how much I was able to “pound” the jig with this rod, and how many bites I actually felt, due to having a bit of tip on the rod, and the pretty fast transition into the backbone.
Some might really like this, and I think it would work well for 5mm jigs or small spoons. For my tastes, I like a little softer tip, and I moved the transition a little further back and slowed it down slightly. I haven’t used one, but my rods seem more similar to the Tuc Precision Noodles based on what they look like on TV. The first 4 inches or so has very little taper, giving the smooth “spring bobber” type action, and either a tick or an upbite is easy to see. Some actual feel is lost, but I have stiffer carbon rods for when I want more control over the jig and want to feel the bite.
I think the first thing to think about is what size/weight jigs you normally use. If normally smaller jigs, I think the Tuc Precision Noodle is popular, and possibly the Thorne Power Noodle but not sure on that. I think the DH rods are just slightly heavier in the tip and would work best for slightly heavier jigs.
Or custom make one yourself or have somebody build you a custom rod to do exactly what you want.
