The reason I said that Breedlove is the best I've seen in the last ten years is because that's how long it's been since I've tried to use a ball-mount. The last several I've had (Radio Shack/Hustler included) I've had break. No, they weren't holding up a 102 inch whip. It was either a 'BugCatcher' or a screwdriver antenna, and they ain't 'small'. The Breedlove mounts will handle things like that very easily.
Something else to think about is that if you think you require a larger backing plate, Breedlove will be happy to furnish you with whatever size you want. You will pay for it, of course. He'll also built a mount to your specifications if you want one. I'm sure that you can guess that you'll also pay for that, right? But Breedlove is very easy going, will tell you if something's possible or not, and will honestly try to help you if you give him a chance. If something he makes breaks, you really must'a used a big hammer on it.
I'm not doing a commercial for Breedlove, he wouldn't know me even if I bit him. If YOU can get him to pay me for doing commercials for him, please do! It'd be one of the easiest jobs I ever got, he does good stuff.
