Weight will be about the same, or a few grams over, that of the 07 Meta5.5. Say about 7.5 - 7.75lbs. Other than the adjustable head angle it's more or less the same as the Meta 5.5, only with more travel, so it'll climb amazingly well. To ride the bike it feels like a plusher Meta5, but it still feels very stiff and firm when putting the power down. The BB is slightly higher than the 5 too.
I've just finished putting
the frames into my shop website, here is a nice big pic of the frame:

Hope that helps.
