Margo, what is considered light as far as carbon goes? The Alpha Q weighs in at 345 grams I think.
I hate to say it but I haven't compared carbon fork weights for a fair amount of time. Last time I did, Reynolds and Easton offered the lightest options.

I have the earlier version of the Reynolds Ouzo Pro UL on my road bike (same fork, more or less, but has a matte finish), and it rides very nice.

I haven't gotten involved much with True Temper as far as forks go, but their reputation is good amongst builders. The sleeve you have to bond inside of the steerer (I am not sure that is still the case) was a turn off for me at the time. Plus, at the time I was comparing, they didn't offer any decent 650c options, which is important for me too.

You know, 43mm of rake is still verrrrry close to 45. If you can get an Edge fork in that configuration and you are okay with the aesthetics, you may be happier with that over the TT in 44mm.
