I've been using the Tubus Logo Titan for three years now. At 390 grams, the fact that it's rated for up to 66 lbs impressed me at time of purchase. The durability of the titanium tubes have impressed me on a day to day basis. It's the most solid rack I've ever owned. The only downside, if it is one, is that the top section is relatively narrow. Hence, many trunk bags are a bit wide to fit well. I've run full size panniers using the upper tubes and smaller front panniers using the lower tubes. Both combinations work quite well.
