Noodles are quite.limp for rip raps.
Like bob said, power varies from manufacturers. I like the 36-42″ range rods. Much better control and more comfortable to fish.
When I’m developing a new ice rod for myself, I look for a specific action in the blank based on weight and stress. For weight, I want to see it loaded ( tip down a couple inches and the blank just starting to slightly bend with about 2 to 3 times the lures weight.
Then with line ran through the guides, I stress the blank to mock having a large fish on it. That will show the back bone and how fast the tip section is. My ice rap rods are very similar in action to a good 1/4oz blade bait rod for open water. Just scaled down. Hopefully that helps
