If the they are thru holes, they bolt increases the weight a lot as it is rather long. I'd Imagine an aluminum standoff with tapped ends is lighter than a delrin standoff with a thru bolt of comparable strength,

That is a very good point. I have actually not thought about that before. One nice thing about a thru-bolt with a delrin spacer is that you could buy delrin round stock and make the spacers yourself saving a ton of money. We spent $150 just on standoffs for our drivetrain last year which used COTS threaded standoffs.
