Found about an equal split between the 2 approaches after much googling. Although some "locked knees" advice seemed based on avoiding quad assistance, which seemed odd to me since, even with a slight bend (and keeping that bend constant), there's no flexing at the knees so how would the quads get involved? On the other hand, the most intuitively persuasive thing I read was in a "pro- slight bend" article, which pointed out that you don't jump with locked knees so why train calves with locked knees?
Anyways, I'm curious what people think about this.
