Shimano DH3N80 vs T785 (Deore XT)
I'm looking to add dynamo powered lighting to my main commuter bike and I'm having trouble picking the hub. I don't currently have the budget for a SON so I'm looking at cheaper options like Shimano, SP, etc.
The bike is a cargo bike (Big Dummy) so I need a 36-spoke hub that can handle some punishment. I bike through New England winters so having something weatherized/winterized that can stand up to salt and muck is a must. Lastly, the bike has disc brakes so there needs to be some compatibility there.
I came across the DH-T785 which seems to be for touring or mountain bikes. It looks like it might be a good choice but I was wondering how it compared to other options, like the 3N80 which looks marketed as a standard commuter hub.
I've read that the SP hubs might not be sealed as well as the higher end Shimanos so that steered me away from them.
Anyone have some recommendations?

DH-T785 and 3N80 look nearly identical to me except the disc interface. I would certainly want discs on a cargo bike
I don't think the Shimano hubs are particularly well sealed or constructed. The SP I have on my gravel bike seems to work fine in that application, and the efficiency and construction quality are much better. Having said that, I have many miles on my Shimano hubs in very bad weather and I have never had a failure. I have the 3N80 and a 3N72. The 3N72 is a little cheaper, but I think it's pretty much the same inside as the 3N80

For what it's worth, I have two bikes with Sanyo hubs, both 36h. They work fine for me.

The DH-T785 looks to be like my T670 rear hub, made for the European market but not the US. It seems to only be available from European dealers based on a quick search. There is nothing wrong with that except that getting service would be a PITA under any warranty. I didn't worry about it.
I bought a DH-3N72 btw and it works great.

+1 for the sp dynohubs, nothing but good things to say about them.
We are running 2:
SP Pd-8 36 hole on our tandem which has @3000 miles and no issues (I ride in rain and wet......as often as we have it in CA)
SP PV-8 on our bob yak trailer (for battery charging)
I plan on ordering a PL-8x soon to use on the tandem moving the PD-8 to my single so I can build it up with a wider rim.
