The industry is split about 50/50 on single versus 2 bolt posts and there are NO issues with 2 bolt posts.
Here is just one thread about it...tip of the iceberg.
Madone 5 Series Seatmast issues. The clamp won't stay put!!! Suggestions?
Also, aside from your pristine shop, BB90 has been problematic for owners as well including carbon shell wear.
The seat design doesn't suck. People who suck at using tools suck.
EDIT: Just for fun, I gave it a shot and googled it. I didn't really find too many complaints, so I'm not sure where your "tip of the iceberg" comment comes from. And each one tends to have 2-3 other owners saying "no problems here" or "use a torque wrench" including the one you linked.
So again, until you actually own and ride a Trek for a good while, I don't want to here your conjecture anymore.
And you know what, while we're at it: what is your "voice of the industry" tag there all about? In what capacity do you work in the cycling industry? I don't think it's every directly come up. I'm not doubting it, I just don't think you've ever explicitly stated what you do.
