I have the 5350SE that came with the same low quality U metal bars. I upgraded to the Tara Labs RSC Link (sometimes known as the missing link) for $35.00. The improvement was well worth the money. The construction of the short cables is not so sturdy, so be careful when you remove the cables. See this link for more info:
