Swiss/football/multigrip bench press bars

My main goal is to lift weights with a mixture of intensities for a long time, so longevity is important to me. I'm 34 right now and have no desire to ever compete in powerlifting, so a strait bar bench press isn't really a necessity for me. I do really enjoy bench pressing though, so I would love to always keep it in my routine in some form. I've recently started getting a little pain in my right shoulder for a couple days after a heavy bench press day. It's nothing crazy that prevents me from enjoying lifting, but I don't want it to get worse. I do my best to retract my shoulder blades throughout the lift and engage my lats, but I know my form is not perfect. Anyways, I've been researching multigrip bench press bars to incorporate as a break from strait bar or to replace strait bar bench altogether. There are a ton of different brands, styles, grip angles, etc. If you use one of these bars for bench press can you let me know how it worked out for you shoulder health and training stimulus wise? Maybe how you've incorporated it into your routine? I also do DB bench press occasionally, but just don't get the same effect as a heavier barbell.

Thanks!
