Figured out what's wrong.

[squeeforever]

Best 17mm setup is probably to get the RD racing knuckles and 8mm axles with some buggy hubs. The Tekno is quite a bit cheaper, and aside from aluminum vs. plastic, I don't think you'll notice any difference. If I'm not mistaken though, the Tekno has 3 adjustments for the turnbuckle, as apposed to only 1 I believe, so if adjustability matters, get the Tekno. I wouldn't really worry about durability either since the Tekno seems to be pretty stout and has the aluminum rings to keep the pivot ball from pulling out.
