Weightlifting is very technical. If you want to compete in weightlifting (or just perfect more complicated lifts than the power lifts), go do it. I'm not aware of weightlifting (properly coached) being any more dangerous than powerlifting - anecdotally, I know more injured powerlifters than weightlifters.

The older I get, the more I want to be a 'jack of all trades, master of none' in terms of fitness, but that's just a personal bias. I don't have the patience or the motivation to ever learn how to do a snatch or squat clean properly, but I see the appeal.
