Grew up using my grandfather's 2-piece rods, and I never had any issues with sensitivity or breakage. Ever since I started making my own money, I've purchased 1-piece rods since most high end rods are offered like that, but if I had the choice to, I would buy 2-piece rods. I travel internationally at least once a year, and I would prefer to carry high end rods with me. I just saw that Megabass released a 2-piece Heritage rod, but that's beyond my budget for now...
