What comprises a beautiful Biellmann spin?

I just have to add a little something.When you look at photos you dont know WHEN during the spin it is taken and also it can look nice in profile but not soo good from the front .Some skaters tend not to hold the leg straight back but a little to the left or right (depending on which leg ).It shows clearly while taken a photo in front position .Bielman is a very hard possition to hold and Irina does a great job .She does not only have in me eyes a nice positions she doesn´t move " on the ice doing it and she is also able due to her good balance to make it both ways .Lucindas and Denise is beatiful too but the most stunning one I have seen is Tamara Moskvinas in 1965 .Just saw it on video.
But here is Irina from euros practise 2006

The above is what Irina looked like at Denver COI believe it or not.

What was the Bielmann called back in 1965?

Well I dont know what the Bielmann was called 1965 but I was sure surprized to see it in that video from Euros Ex 65 perhaps more than I thought it was stunning .
