I have trouble with the who's who of French ice dance, who is this all supposed to benefit?
Good question.
That's easy, it's the school of Lyon.
I'm sorry but I'm gonna go back a while.
From 1996 ? .. to ... 2011 ? (around this period), no good junior french dancer was authorized to go anywhere else than Lyon.
Gailhaguet was backing the Zazouis.
Even the second ice dance school of Lyon in Baraban was complaining about it (namely Lydie Bontemps when she had to let Delobel/Schoenfelder go) but eventually, everyone "surrendered" to reality.
No coach outside of Charlemagne coud develop anything.
When Arribert arrived in junior around 2005, things started to get heated between her and Lyon.
She had one junior couple who was doing reasonably well internationally : Zoé Blanc / Pierre Loup Bouquet
And they wouldn't leave her.
And at times, Blanc/Bouquet would beat some of Lyon's best junior couples, like ... Elodie Brouiller and Benoit Richaud.
And Lyon didn't like that.
And many of the "rejected" ice dancers, the "not good enough for Lyon" started to go to her.
That's how she started to build up her school and to become kind of "legendary" because she "embraced" those kids and their journey in ice dance and gave them the best programs she could.
And despite not being the best (and falling quite often), her kids were popular, thanks to their programs and their total investment in what Arribert was giving them.
The minute she reached the senior international level, things became very heated.
There were repeated pressures on Blanc / Bouquet to leave her.
They were threatened about selections to international competitions.
An international judge told them Arribert was dangerous for their career.
They were deemed "different ... too different".
Arribert said how her first (and for long only) Worlds (2009) were a nightmare.
In the end, in early 2011, Blanc/ Bouquet chose to leave ice dance entirely.
Arribert got back to her mountain to her "not good enoughs".
In 2011, Gailhaguet changed his mind about Lyon, finding the Zazouis too powerful within the fed.
It took him 3 years to tear Lyon down, not helped by the fact that Papadakis Cizeron chose to train there for 2 seasons.
By 2014-2015, it was clear that Lyon was dead.
Then Arribert and Piton started to build the centers that we are now seeing in action.
One can wonder if they carefully waited for Gailhaguet's demise (2020) to take the light.
OTOH, it took quite a while for Lyon to get back on its feet. For long, they tried to go on as usual, getting good juniors from other centers, pairing them and going international with them. It didn't work. Of course, Haguenauer had left. Neil Brown also left...
Then they realised what Arribert and especially Piton were doing locally.
As they knew rivals were coming up, they built a development program from the scratch, from the youngest categories up, with the support of friendly centers (Ambre Perrier Giannesini was trained by the Delobel sisters).
And they are back with very solid ice dancers ...
But they are not alone anymore.
There are centers on their way who have cemented their existence and their value in ice dance. IMHO with an added value that Lyon doesn't have in terms of creativity and couple building.
But there is something that Lyon has : friends and former ice dancers.
