Maybe its not the bands, but the watches that are holding everything back. Because there is a smaller number of people wanting the LL there is a smaller amount of feedback on forums. Though I'm sure many people ordered at xx:03 there might just be more people that went with SS BSB, CB, then LL. There are probably quiet a few people out there that have them, we just don't know it because they aren't on here.
To back up my thought, look at the stainless band poll on this link.

I think more people come here than fill out any poll. I don't even fill out polls that are here...
I've looked at results of some, and they aren't consistent.
Just my opinion
