I will take light weight, strength, rigidity, dimensional stability and efficiency, hydrophobicity, impact toughness, and low cost any day

Coz the manufacturers can't spell c-a-r-b-o-n f-i-b-r-e yet, and are slaves to marketing bunkum

P.S. I would agree that design for the unlikely event of a bin dropped on an eyecup is of less importance than the quality, 'feel', and functionality of the eyecups in usage - which should be commensurate with the level of the asking price. By all means design a sacrificial eyecup assembly in the event of an accidental drop, but not at the expense of the quality of the functionality in operation.

I found the eyecups the most low rent part of the SF, and difficult for me to set up satisfactorily. I would suggest the OP try these out in person and see how it works for them. I wear glasses and have to back them out just a smidge - other people will be different. What counts is how it works for them.
