Nonsense; he's had to reign in his energy level. Noelia is a beautiful dancer, but I think she's a ball and chain for Carlitos..I don't think he's ever had any problems expressing nuances.
He's had to work hard to let her fit in her decorations, which I think works fine, but at what cost?
I just joined, and although I dont really enjoy tech analysis of tango, your discussion made me jump in... although its bit late comment in this thread

I completely disagree anyone who says that Carlitos' & Noelias' dancing is simple. Its very complex. Yes, looks easy like all the difficult things made with great proficiency. Perhaps because we don't see many ganchos and other cheap show tricks etc. But their dancing is super-speedy, perfectly balanced, while both have space to play and suggest. Also, they very often dance on the nearly full range of the particular music, beat + melody and pronounce different instruments. Guys, there is nothing simple here, see how Noelia accentuates the rhythm and how Carlitos leads many even barely noticeable adornos.... The lady has probably a pair of nearly fastest feet among tango professionals at the moment. Like Geraldine before baby. Like Andrea Misse before tragic accident. But luckily Noelia has her own style so she is there in the list in her own right.
I also find that Carlitos contains her beautifully and the flow of energy between them is intense, fresh and genuine. He contains, controls but gives space underlining her strengths. Really amazing. I think Carlitos has upped his energy a lot and his dance is completely another lever compared to when he danced with Mamie. Not that he was somehow uncapable before, I just think he met his equal match and even a bit of a challenge.
Mamie is a very beautiful dancer, such joy to watch, but different level compared to Noelia completely. Mamie is still a social dancer, amazing, natural talent, fast learner, but hobby dancer. She has a vocation, tango is not her first calling. Noelia is a professional, with many more years of experience. There is a clear difference in speed, precision and vocabulary. And what's the most exciting about this new tango couple - Carlitos & Noelia, they've established their style and quality in a very short time. In a year, thats pretty unusual, really looking forward to see how they grow together!
