Scanspeak r2904/700000 or the new Focal tb 872

I know my best bet is to audition both of them, but i wanted to hear first opinions and tips from our fellow diyma gurus..

As stated in the title, im trying to decide which is better in terms of sound,build quality, overall value etc..

I've seen and heard a lot of good reviews for the ss r2904/700000 tweeter the only concern that i see with this tweeter is that its really big and might be a PIA to install..on the other hand the tb 872 is new, an updated beryllium tweeter with a more user friendly approach..

Anyway for those who had auditioned both of them, kindly help a guy decide which is better, all opinions are welcome..

Thanks diyma..
