I've had the occasion to use one recently and was amazed/unhappy at the size of the rockerbox and the weight. I look after a club-owned 17.5" that has a smaller footprint than the GSO 16s! And the 17.5" is easier to transport - you need a big boot to fit the GSO rockerbox in.
I didn't notice any of the upper cage movement using only the three struts but then I was concentrating on just what was needed to get it working that night I tried it. The optics were fine. Was easy to collimate although there was a bit of slop in the focuser. Balance could be an issue but there is a way to adjust it, but not at night! It looked a bit fiddly. The GSO scopes in my experience have always been difficult to balance without modification.
There are no shrouds available for them yet, either.
