wether the springs are “helpful” actually has a lot to do with the frame as well as the person sittting in them. (Not getting into the debate about what is perceived comfort vs what’s actually good for you medically speaking) But the springs in brooks saddles actually have a weight limit, and if you’re, by your own words ‘obese’, you’ll probably bottom them out, making them useless. I’ve always hated them, mainly because they always squeak and it’s damn near impossible to make that completely go away. I wouldn’t be surprised if most people, even back in the 1890s found them uncomfortable and annoying.
