I am no rod expert but I have had a bit of experience with telescoping rods. My friend had one and I decided to try using his. I instantly didn’t like it. The guides wouldn’t stay straight, it wasn’t super sensitive, and it wasn’t balanced at all.
It might not be a problem depending on the brand. I would recommend going for a three piece rod. I have heard good things about the Fenwick Travel Rod. I am pretty sure St Croix and other brands have them as well.
