Both are good knives and I own both. The LCC feels heavy, because it has a large chunk of metal in there for the spring. Too heavy for me for a knife that size and no guard for the hand. My hand has already slipped onto a blade once.
Dominator is the right weight for a small knife extremely strong lock and extremely sharp. As far as hard to open? Adjust the pivot and there is no problem. Also, the way the spring is set up, you will have a hard time getting that puppy to open by accident. It has to get to 30 degrees to hit the release point on the cam. If it doesn't make that, the blade will generally suck back into the handle. I watched some of the testing on the prototype and when the knife was dropped from about 5' with the blade open at abou 30 degrees, the blade wnet back into the handle. No, it wasn't dropped on the blade, it was droppedon the ends and on the flats. Plus, it does have a finger guard, no slip, no cut.
