The reverse cone Emgos are the ones I went with. I can't comment on them yet, as my bike is still in pieces, but they certainly look nice, despite how cheap they were.
This was one of the videos in the link you provided above. It's nice, from what I gather, they're comparing the sound of the stock mufflers to the Emgo's, and then to the Hoskes.
I'll have to hear the Emgos for my self once my bike is complete, but if this video is a good representation, I could definitely see a set of Hoskes coming my way in the future!
