I like broad nibs and I cannot lie

So far I've adored medium and broad nibs from both Lamy and TWSBI. I prefer the broads from both brands. I have a few italic/stub nibs, but I prefer rounded nibs to stubs.

I have it in my head that I can't get enough wetness, and I leave my bullet journal open at work and seldom have to consider drying times. I'm just wondering where the love of broad nibs becomes ridiculous and I have to dial it back down.

I'm not sure where to find a double broad nib. How many popular options exist and what are the drawbacks to writing with the wettest nibs out there?
