I think doing bench is a bad idea especially with heavy weights. Once you get over roughly 35 years old, you should be doing dumb bells. You can go heavy the dumb bells if you wish, the thing with the dumb bells is they give you free range of motion. Our joints are very complicated and holding a bar that has no give doesn't allow for proper rotation of the joints. I never barbell bench, I did one day a week ago, the day after I did the (almost) 315lb military just because I was curious, but even then I was going to see how many I could do at 225lbs. BTW, I got to 14 and just ran out of gas (lol at getting old).
Lastly, when you use a barbell you have no ejection plan with no spotter; with dumb bells just let them go and hope you don't hit someones feet.
