any recommendation on which choice i should make for my new frame? ive test riden all of them and am aware of how each one feels but i guess it boils down to which one i like the most.

Ridley Noah
Scott CR1 SL
Cervelo Soloist Carbon
Orbea Orca 07

btw, im slightly inclined towards either the noah or the orca for its wicked looks... any comments on the others?? which do you think look the best?

If it were me I'd go with with the Noah. I saw one with Record, Lightweight's, and other various superlight plastic bits at Spinn Sykkelshop, but at 65,000 kroners (~$11,150 w/ current exchange rate) the guy wouldn't let me test ride it without a look at my bank account.

Rode all but the Ridley and can say the soloist has my vote. Wish they had a zero offset post for it. I would buy one if it were not for that.

Looks alone? Noah, hands down, for me. Have never ridden any of those bikes, so that is a pure appearance only vote.

Is it me or does the ridley look an awful lot like the Giant Advanced? One Compact vs another.

All good frames, I could be happy with any of them although I am not partial to integrated seat posts. I have a Scott CR1 Pro and I am very happy with it.
