I have dimension doubles because they were cheap. Thats what I needed at the time. They have been fine for a month now. I do want Toshis and have no problem forking out $110 after feeling them and understanding how much superior they are (being layered and strong). But calling the dimensions dangerous is funny. Bicycling is dangerous. If you break a strap and then crash into a bus head first because you can't stop... well, then it must be dimensions fault for making an inferrior product to Toshis. LOL
