There are and there aren't. Many people review and comment on items, not many people do a full on formal review. Google search without quotes "site:backpackinglight.com smd swift"
That'll pop up people who have had questions, and people who have given opinions.
Also, since it's what got me to purchase mine, and also given my hetero man-crush for Stick (the well informed prolific reviewer who buys everything I want, have wanted, and want-to-buy-but-didn't-know-about), http://sticksblog.com/gear/my-current-gear/backpack/six-moon-designs-swift/ is a good review, though I don't think it's necessarily the latest iteration of the pack.
