Are you having problems with your Gamma starting clamp?
I have two of the RAB ones, which I believe are the same ones GSS sells. I find them excellent.
Starting clamps aren't the most complex tools. You're pretty much looking for something that:
- doesn't slip
- doesn't crush
- is easy enough to open, without being too easy to open
The other variables are whether it has eyelets so you can use it as a jumper (mine do), and the width. I've never had to use it in a tight space though, so width isn't important to me provided it meets the above criteria.
If your existing starting clamp ticks all these boxes, then you have to ask yourself what you'd gain from owning a 'better' Babolat model.
