Having said that, I still prefer to use 6-7-8 speed chain for this application, usually SRAM 850. It's relatively inexpensive and lasts a long time.
Per this advice I replaced my Suntour freewheel with a zinc Sunrace 13 28 and used a SRAM 850 chain. Wow it shifts like butter and indexes perfectly. I added 2 links over the stock chain length.
