I'm building my first bike, a 105 Soma Smoothie 58, but am stumped on the headset. I purchased a Columbus Tusk Air fork, which calls for an integrated headset to mate with the frame. But the frame is not configured for an integrated headset. From what I can gather from the interwebs, It appears that I can use an integrated or non-integrated headset, most people say it doesn't matter. Which type is best to use? What brand would you recommend, in a mid-range headset?
