Damn Brutus, you are built like a tank bro!!! I believe you can press those 150's. That's pretty damn impressive. My weak ass can only do 120's for 12, haha. As for military and db presses for shoulders, I think that once we get old, we won't be able to do them anymore. I can still do them just fine and my left shoulder cracks but I don't have pain. A personal trainer at my gym who's a pretty big dude claims that he regrets ever pressing 150's back in his hey day and says that's what wrecked his shoulders. I'm shoulder dominant anyways so I think I can get away with inclines and lateral raises.
