haven't tried my look alike bob trailer as yet.i have just finished my project on turning my Raleigh road bike into a light weight tourer. it will be used to pull the trailer ,the tubes in the bike are reynolds finest 753 and way to light for racks /panniers.When i load up my thorn with front/rear panniers it's a dog on climbs (don't know how to add smiles)
so like yourself i'm dead curious to see which is better.
