Yeah, that's why I'm asking about a dual-45*, would that be better than a single 90*?

Okay, here's a thought experiment that hopefully someone can answer....what's the best way to get a 90* change of direction with a given radius? A variable diameter arc? An decreasing/increasing radius arc? Dual rounded 45* bends (giving a straight shot for an inch or two to reduce turbulence)?
