Cebulla M Strap for Saxophone Standard

I have not yet fully tried the Celluba neck strap for my alto saxophone but so far I have found it very comfortable. I decided to purchase it after reading about it in a book on saxophone maintenance and it 's description seemed to cover the problem that I have with other forms of strap. The normal strap made my neck ache and the body type of strap felt restrictive around my chest. I am 82 years old and started to learn the alto 4 years ago so at my age any help towards comfort is acceptable.
