Hi Anga!
Sorry you were neglected; thanks for the little nudge.
I'm afraid my Sherpa and Nomad both used Rigida Andras. I was/am very happy with that choice for expedition touring, but they are very heavy rims for more standard uses.
My other bikes predate current rim offerings and include a variety by Ukai, Araya, Mavic and even Alex that are no longer available. I have not personally owned the Zac19 or Grizzly rims.
I can report a Dutch pal has put a lot of distance into his Zac19s and is still very pleased with them. I have seen them firsthand and know them to be a quality rim. For reference, he weighs 86kg, his bike weighs 17kg, and he carries as much as 28kg while touring for an all-up weight of 131kg/288lb. He's found the Zac19s to be both reliable and durable and has yet to go through the brake-track wear indicators, despite many uses in Dutch rains and a round-trip to Santiago de Compostela.
All a bit vague, which is why I didn't answer right away, but hopefully something in the above will prove helpful.
I think either the Zac19 or Grizzly would suit your needs nicely, but I'd probably lean toward the Zac19s because I've seen them and a friend has had good luck with them.
Best,
Dan.
