My VPI counterweight weighs 150g; the CI weights about 20g. Rotating a 20g drop down weight around a fixed axis will allow for a finer azimuth adjustment than rotating a 150g weight.
If you are a person who likes to adjust their azimuth to the nth degree, go for the CI, otherwise the standard VPI counterweight method will suffice.
