I went with the Tubus Nova.
I like the idea of stainless due to no paint to scratch and resistant to rust.

With regards the Surly, tis too heavy for what it is and can carry.
A combo of Tubus front (any of them) and something like a Velo Orange Pass Hunter rack

will both (in combo) weigh less and carry a much higher kg load than the Surly.

As for Canada, not sure what your import duties etc. are like, but here in Aussie availability can be a challenge for bike parts, not to mention price rorting, so I tend to buy most of my stuff in Germany.
Buying from the EC (from a non EC country) means no VAT (tax) to pay and here in Aussie, no GST (tax) or duty for bicycles/parts less than a thousand dollars currently.

I use bike24.net and starbike.com

Good luck with the purchase decision and finding what you want.

Spotted a nice LHT here with the type of top rack I was waffling about and with my favorite Gilles Berthoud fenders which I have on my Ogre.
The photos dont show a low rider so you'll just have to imagine a Tubus Nova added in your photoshop imagination.
