I finally wore them for my practice (hard court, 2 hours).
They defintely felt different than the barricades - somewhat lower and a lot lighter. I really liked the straps on the ankle and the top of the laces, it worked great during the practice and since I like my shoes tight I found the straps really useful. The traction was really great, and in a way I liked the Propulse's traction more than the barricade's. However, it did take me about 30 minutes to break in the shoes, as they felt less cushioned than what I'm used to play with. I can't really comment on durability since I just bought them... but they do have 6 month warranty in case you need it.
Overall, it's defintely a great shoe, and thanks to the Babolat discount I got them even cheaper. But make sure you go try them on, because I think that these shoes are narrow, and won't be as good for players with wider feet.
By the way, I agree with pmacino's colour description...
I didn't really have enough time to try them out, so I'll let you know of any other updates.
