As Chris suggests the Tsubaki Sigma chain is excellent.
I used DID for years, and have no problem with using it again, it's just that Tsubaki is, IMO, so much better. You could tow an oil tanker with the 520, god knows what the 525 would be like.
It's no more money either.
If you prefer the DID, then you could buy Afam chain. This is DID in a different box and costs less.
