 The simple model has a very simple bridle system without pulleys and with less attachment points on the wing. 
 While the default model has a [speed system](https://kiteboarding.com/proddetail.asp?prod=ozone-r1v4-pro-tune-speedsystem-complete) with pulleys and more attachment points on the wing.

+```
+using KiteModels
+
+# Initialize model
+set = load_settings("system_ram.yaml")
