Well I probably am a closet weight weenie myself. If I was to get another stem, it might be Wrens. I don't see anything about them that screams cheap crap for more money. And the one and perhaps only commonly touted incident seems to be more about failure that could have been caused by overtightening the bolts and stripping the threads. And then continuing to use the stem. And that's deserving of a Darwin Award for that person, if that was the reason for the failure.
Weekends are slow here. Maybe more will take notice that might have experience with Wren when Monday comes around and everyone is looking for something to divert their minds from the drudgery of their job. <grin>
