The 36t cassettes were designed for the 29’r and with a tiny chain ring Sixty Fiver is correct you can get one heck of a lot of output torque depending on how hard you are mashing. On the other hand if I had the engine to rip the spokes out I wouldn’t need the 36. For me it’s a tool for someone that wants to stay in the saddle and spin up a tough climb off the granny. I tried the 36t with the 22t ring and for me it had me saying something I didn’t think I would ever say and that is the gearing was just too low, or I couldn’t spin fast enough to keep the bike upright. So in my case there can be too low of a gear. Spinning that combo produced a speed about like pushing and I actually felt pushing would be easier at that point. I used a 26t granny with it and last summer tried a 24t and found that to be my absolute low gear.

I like that cassette as much if not more for what it gave me off the center ring as a range of gears. Like the OP using the bike for touring as well as all around, and in my case my old sluggish motor runs at a lower RPM but still puts out a fair amount of torque. I won’t say I’m a masher but my comfort zone is a good 10 RPM lower than when I was younger as well as the speed is dialed back a little.

In my case my perfect touring GI off the center ring would be around 30 to 70 GI, but my perfect recreational riding without a load would be around 40 to 90 GI.

That was my biggest concern with the mountain bike crank for me it gave me a great loaded gear range but fell short on the top end at least without making that front shift. I needed the 42,32,22 for touring and liked the 52,42,30 around town even though I had no use for the 52 for the most part. That’s where the 29’r cassette let me have it both ways with a few adjustments to the rings.

That was for me and each person has to look at it based around their torque and spin preference. The op might have a naturally higher cadence or if not won’t find making that front shift more often to be any problem and getting that lower climbing gear well worth the tradeoff.
