OK so after about a week of having this on the back - my biggest criticism is that I miss having it on the front.
Have completed multiple 13km runs with Arkel GT18's in back lugging 10 liters of juice in the side bags and a 4 liter can of WD40 in the top bag. Thats about 15kg total, well within the rating of the rack and definately more weight than I'd take touring myself.

OK so I really went shopping and picked up a few specials.Maybe my 'touring testing' is a little unconventional by some standards, but this isn't a paid review and since I tend to use a bike as a pack mule whether I'm touring or not - these are all practical tests IMO. I've seen many alloy racks (particularly on ebikes supporting a battery) have the rack stays collapse because of a heavy load and am looking for long term durability in spite of some abuse.

In case anyone is interested - I also personally own and use Axiom Journey racks, Specialized duo racks (front and back) including their 'Six Pack' front rack, Old Man Mountain 'Cold Springs' racks front and back, a Topeak rear beam rack, and a couple OEM Velec ebike racks including a two stage unit specifically designed to house a battery while keeping the top rack platform free. Some were less than $50, a couple were over $150 and am still looking for something generic enough to do anything but specialized enough to do it well.

I happen to like these racks and am waiting for a second to test a dual installation front and back. So far they're the only thing I've found that fills the 'go anywhere /do anything' criteria I'm looking for. On the other hand the Thule bags don't personally hold any real interest for me - I prefer the Arkels I already have. Will post some photos as general info in case some people actually find it useful. If a few people still think their are ulterior motives - hey - you can always skip the thread.
