Are there two major schools of International Rumba?

I recently discovered some of Allen Tornsbergs teaching videos. For example:

The more I study them, the more I like them. For example: The accent on 4 in Rumba, the moderate hip movement as opposed to the exaggerated movement many teachers prefer. I always thought that exaggerated hip-movement is OK for the lady but looks a bit strange on the man. Allen seems to confirm that.

Rumba Walk. Allen transfers the weight on the exact beats of 2, 3, 4 right away, while Slavic goes through a split-weight position on Rumba Walk (in his teaching video with Karina). It seems there are two schools.

All opinions would be highly appreciated.

Technique, in Latin, has moved into different directions over time. Going from Pierre, Thru Laird , Hancox etc.to todays proponents .

I would certainly agree with this.. The mans CM in latin, needs to be more subtle and not as overt as the ladies; and as to a stress on 4, thats a Son dominant expression, and moves closer to Clave.

To remember.. latin,particularly, and its "style ", allows one much more of a personal choice, than does Standard .
