You know it's funny , I want to thank you for pointing out metal militia to me. But now I'm using metal militia against you
The metal militia bench press technique is a power lifting technique that uses a narrower grip, arched back, drop barbell low, etc... Such a technique will reduce shoulder rotation but will place more stress on anterior delt and tricep. Having said this you will be placing much stress on your shoulder while benching. I would agree that side laterals shouldn't do much stress to anterior delts, but why not just do all the shoulder excersizes on shoulder day?
You said it yourself , metal militia doesn't recommend it , and neither do I.
