Neat bunch of 'hits' you brought us, Sig.
The subject matter was/is always a favourite of mine and more is always welcome.
My humble opinion is that, you'll be on/off/beneath stage, dancing and shooting photos of your projects for quite a long time with your particular diligence, hopefully.
You appear to be a favourite of your colleagues too.
Thanks for sharing your thorough experiences with the equipment and ballet in general!
