What are the opinions of most of you related to the photo clam ball heads? I personally use the 48NS and I'm loving the quality and smoothness. I bought a few extras because I thought I had a couple people wanting to buy them but they bailed. So now I have 2 for sale on the for sale on the forum. I have a 54NS and a 48NS for great prices.
I much prefer the non proprietary option of the sidekick along with it better design. A true balanced gimbal that is usable across a fair spectrum of non related ball heads. The BV option on the markins does make for a neat pan & tilt option on their product exclusively but doesn't even transfer by model in their own line. $269
