Hmmm... I don't think 18 minutes worth of 30 second subs really cuts it. Clouds stopped play :-(
Still the set-up worked. The Tak is quite 'bouncy' sitting on top of the C9.25. But the vibrations die down quickly enough.
I've ordered a 7lb Losmandy weight as well, which I'm assured will fit onto the CGE counterweight bar. Two 25lb weights work, but are a tad heavy for this combination.
