Thanks Brian!

I ended up going with the Stay-Lok as I have used them previously for smaller rigging and that they have been around for awhile. It turns out Oyster uses the StayLok at the moment as the baseline for the 575 and below which means easy access to parts when cruising (Oyster customer service is amazing!)

I was very torn considering the HyMod fittings but decided to go with something with a bit longer track record at this point. I also looked at the cost of the wedges to go back and forth between metric and imperial, their wedges (which are reuseable) are rather expensive compared to the StayLok wedges. The castellated spacer is the same for metric and imperial for the sizes I am looking at. It was definitely a close call at this point to go either way.

Thank you again for your recommendations. I really appreciate your feedback.
