I'm touring with a Tubus rack at this very moment actually.
They are good racks, no doubt. Not the best price to performance ratio though.
Good good!
I mean they are an excellent price to performance ratio they work really well and last a long long long time I cannot really say they are poor price in that situation. They are quite lightweight and hold a ton of weight and have good support behind them that you probably won't need. There are tons of racks but for touring but none I would trust as much as those beyond custom made racks but those would be more expensive.
