I've recently ruined a few good kill streaks because I clenched the controller a bit too hard during a high tension situation which, of course causes me to knife, thus canceling out my shooting and its gotten me killed many times. I don't recall being prone to this problem before but lately when I'm on a roll, and I have to flee or turn around really fast I'll grip the controller too hard by mistake.

So I've been debating about switching my controller setup to "tactical" so that if I do accidently "clench" I won't knife but rather I'll begin to crouch, that wouldn't be as interruptive and may even save my life. On paper it seems like a good solution but does anyone else have this problem? Do you have any tips or advice? Would switching to "tactical" solve this issue?

I know Halo Reach has a feature called "clench protection" which you could enable, that made it so you had to click the thumbsticks in a bit longer than normal so you wouldn't unintentionally do anything, like zooming or crouching. Since MW3 doesn't have this feature, I figured perhaps changing to the tactical setup would function in the same manner as Halo Reach's "clench protection" and save me from screwing up my own killstreaks lol
