Mantus Anchor Swivel

I've decided to try the Mantus Anchor Swivel on my system to alleviate some chain twisting I've experienced over the years. From all I can read they are stout and not a weak link. I used the S2 or size larger than is recommended, as it still fits my 5/16 HT chain. An interesting characteristic of the Mantus Swivel is the oblong pin that goes through the chain. It's a clever, simple way to get more metal in there for a stronger pin.

Here is my current set up, looks sharp and should work well
