All of the above prompts me to ask about elbows. Specifically, it's my
impression that tight 90 degree turns aren't a good thing, open, large
radius turns are. However, for the life of me, all I can find are
tight, 90 degree elbows. Got any sources for either a pair of 45 degree
elbows or large radius elbows, preferably in plastic of some sort?
