I may be stating the obvious here, but whatever your setup, it should provide that when you, on the weather side with sheet in hand, put tension on the sheet, it should release, so you can ease it.
When you re-trim it after (we hope) avoiding that knockdown, it may require your foot as well as your hand to push it down and re-cleat it into the cam, but that's a price you should be willing to pay for being able to ease it in a hurry.
Some blocks are rigged "upside-down" so you have to "snap" the sheet down to get it out of the cam cleat. Not a good idea. It should be easier, and more "intuitive", to have it release easily, even if it re-cleats harder. Most mainsheets, I think, are set up this way. Hope so, anyway.
