x 3 on video. But I will also say this:
the answer to your question is all going to be based around your goals. Becoming the best powerlifter you can be can sometimes be a VERY different path that lifting to be fit, healthy, big and strong. If your goal is to squat the most weight you can, period, than maybe your ultra wide stance is the way for you to do that, even if it is going to beat you up.
However, if you are mostly concerned with general health, balance, strength and fitness, than a more moderate squatting style is probably better. Maybe you won't be able to squat 500, but if you can do some reps at 400+ with a stance that uses a fuller range of motion, and doesn't put so much strain on your joints, you will probably feel better overall, healthier, build a more balanced physique, etc etc.
Powerlifting is an extreme sport. Obviously there are ways to stay healthy while powerlifting, but the truth is if you want to move the most weight possible in the big 3, you are going to have to push your body to the limits, which is going to result in aches, pains, and chronic and acute injuries. I bet you'd be hard pressed to find a single truly great powerlifter who doesn't have aches and pains to this day, even if they no longer compete. The question is, is it worth it to you?
