Hi Andy
Are you noticing any problems with your controller?
If not, you probably won't gain much by changing.
One problem Economy resistors are prone to is the wire moving around on the resistor - this can lead to failure. Further up the Parma range, the resistors have the resistance wire bonded on, but the don't on the Economy hence the problem. No point in replacing the resistor if it's working well, but if it does fail it would be a good idea to replace it with a better one.
