Well, all that came with the new chain I rolled in the 560 was the little clips. "C" or "E" clips, whatever you want to call them, two of them were in the package. I couldn't even source a crimpable master link through the dealer.
I used the small clips and after almost 14K miles have had no problem. The small clips do need to be installed correctly, just like the old fashioned single "C". Make sure the open end of the clip is trailing. That way, should the clips make contact with anything internal, they will be driven on rather than knocked off.
The two clips are small and easily dropped. Be sure to stuff a rag in the head at the timing chain passage to catch the clip(s) should you drop one.
