DD I am going to jump in and be the one to disagree with you. I will admit the Gamma starting clamp will not hold as much tension as my Bablot clamp will hold. I did some testing once and I think the difference was quite large but don't recall. But the Gmma is easier to open, crushes the string less, and has never failed me in any application.
Of course i've owned my Babolat about 30 years and the Gamma about 5 so time will tell. No matter which clamp stringer may get they well be better off. Two is actually better than one and you can get by with none - how funny is that?
When you're dead you don't know you're dead. It's the same way when you're stupid.
