Hi Everybody,
Long time lurker, first time poster!
As the title says, I’m seeking advice on converting my current Surly Big Dummy using a BBSHD.
I’d like to run an IGH, and am thinking of going with the Sturmey Archer RS-RK3.

I think lacing that to a Sun Rhyno Lite or a Cliffhanger would do the trick as far as carrying capacity.
Are there any downsides to also using the Terracycle chain-tensioner with the Bafang?

I’d like to upgrade the brakes to a set of hydraulic. I see that Surly is using Tektro Orion HD-M745 on their new Big Easy:

But the reviews on these are mixed. Any strong opinions out there? Any suggestions as to particularly good hydraulics? Would 180 rotors do the trick, or should I go bigger? And, would it make sense to get hydraulics made for E-Bikes in particular?
Finally, any suggestions on chainring and rear sprocket pairings? I am not interested in speed, but rather in torque. I need to get up hills while loaded. I’m comfortable chilling out at slow speeds and enjoying the scenery more than anything. My legs are just getting older, and I want to be able to use this to haul our camping supplies (or, occasionally, my wife) over distance and and over rolling hills.
Many thanks in advance for any thoughts, suggestions, criticisms, etc.!
