I have an excedy twin plate in my GTST which is my daily driver, and I now I really like it. But at first I was exactly like you and hated it, the rattle really pissed me off (now I dont mind it) and it took me a good month to become 100% efficient with the on/off nature of the beast(hill starts in the wet were a killer).
But honestly now I love it, drive yours for a while, get use to it, enjoy it.
