I wanted to really dial in the offset, but there isn't much room for play with the 10s. And I wanted to play it safe with the fronts. I paid 335 shipped. I just went with them because they were cheaper than the HR after shipping. Eveywhere online had ridiculous shipping on the HR, plus I have heard great things about Adaptec.
