True twin plates are never going to be as good as a single for very quick gear changes as you're attempting to release 2 driven plates as opposed to 1.
However, we don't have a drag strip and grip racing doesn't require the lightning fast changes that drag racing does, hence why I went for the Coppermix Twin plate......which in actual fact, is not a true twin plate (ie. with intermediate plate) cause it uses a single sprung Boss Drive. The other reason I went this way is cause of the lighter diaphram that you can get away with and still get a greater clamping pressure.
I've never ever liked solid centre style driven plates or the metal button style ones either cause they're not forgiving as a daily driver. Also double diaphram pressure plates used to be the rage years ago but your left calf muscle needs to be bigger that your right, lol. Drivelines also hate these 3 style of setups.
