[COLOR="DarkRed"]I agree...some mount brackets...like the Gretsch or the Ludwig Standard...also early Tamas...had small contact-points...meaning the rod would only be held there by the screw tension up against a small surface area.
As opposed to, say, Luddy and Slingy and even most Pearl brackets, which had 3 wide contact points (the screw or button, and the 2 end holes of the bracket..further away from each other than a Gretsch) so they hold the arm/rod much better. So, even though the Gretsch is cast, which makes the entire bracket stronger, its contact point is still small.
Personally, I wouldn't try anything heavier than a medium 16" on it, or maybe a very thin 18"...talking like a 1200-1300g cymbal here...I think if you do, you are really taking your chances.[/COLOR]
