Anyone use a Rollmaster timing chain?

Does anyone actually a single row timing chain?
My 71 Honda AN600 used a single row timing chain.....and there are still silent chains out there, still work great.

The construction of a silent chain is 25% stronger than a double roller. Look how many plates a silent chain has (4 or more) compared to the 3 (minimum) of a double roller. I have a silent chain on my tensioner equipped 273, tight as a drum.
