I too have been using a Hercules stand for years, despite it looking a bit awkward it grips the bass well and the small size is great.
A word of warning though, the pivot of each arm that hold the bass on mine have been exposed and the hard tips have destroyed the finish on either side of the strap button on the back of my basses!
I'm not too precious about instruments that are used a lot but this was annoying when I eventually noticed it.
