Rigging scale for 1/85 Frigate

[DDoan]

I am a beginner modeler working on my 2nd build. The vessel I am working on is the Occre Nuestra Senora De Las Mercedes 1/85 scale Frigate. I'd like to make improvements to the kit and i need some advice. 

 

The main thing I would like to replace out of the kit is the rigging. I'm looking at some scale ropes. There are tons of options for sizes so I was hoping someone could give me some insight to what size scale ropes i should use for  the standing rigging. 

 

I found a site with a calculator but I also wanted to make sure it's a reliable source.

Any help is appreciated!
