I hate answering your post because your avatar scares me LOL, but I will anyhow. I use the pinned hinges in my GP Super Sportser 120 (Old Great Planes Discontinued Kit) which was notorious for flutter. I added a counter weight to the ailerons after a good fluttering on the first few flights with it which solved the problem. During the 2 flutter episodes the pinned hinges held up well, and never gave way. So I tend to believe they are fairly strong even under some tough stresses. I run small screws through mine, but the toothpicks would be just as good I would think, as I see alot of people who use the toothpick method.
