I ride a Specialized Fatboy which is essentially a mountain bike but I only use it on the roads, with tires for that purpose.
I recently installed a new cassette. Original equipment was a Sunrace 10 sp 11-40. I got a new one from my LBS but I'm not happy with it because when I change to a higher gear (smaller cog) the chain lands on the cog with a loud clonk, through the whole range of gears. The original one gave a bit of a clonk but not as bad as this new one. I adjusted the derailleur from scratch, setting the high and low limit screws, first. The barrel adjuster is at the lever shifter so I can adjust it on the fly. I can tighten or loosen the cable until the changes are rough. No matter what I do, it clonks. Changing down to a larger cog is smooth.
With past bikes I've had good experiences with Shimano Hyperglide, with silky smooth changes up and down. So I'm trying to buy a Shimano HG 10 sp 11-40 cassette. It seems few sell it, but they offer 11-36. The one place that sells what I want is out of stock and they don't know when they'll be in, so I left my email address for them to notify me. I recently read, somewhere, that all cassettes now use the Hyperglide design. Apparently, that's not true, unless the new Sunrace I bought is an old model.
I calculated the gear inches with a 36 T cog and a 40 T cog. The 40 T gives me 26 gear inches of travel, and the 36 T gives me 29 gear inches. Three more inches of travel in the lowest gear doesn't seem to be a big deal. And if I really need a lower gear, I can switch to the smaller chain ring. Am I asking too much to want the 11-40 T cassette in HG? Perhaps the reason why the 11-36 HG is available in many places is because there's little demand for the 11-40 HG? People who use a mountain bike for rough rides may not be bothered by a clonk with a Sunrace cassette, but on the road it's just loud!
What would you do about having a smaller large cog?
