he he he he you said lube hehehe
but seriouly am keen to hear the respondses to this.
I have 6 pullies and have just recently sprayed them with silicon spray($10 a can)and it seems to be doing the trick nicely.
I think that would be all you need,as long as they are lubed and running smooth I dont think brand or type would be making much difference.
hehehe lube

Its more fun haveing a well lubed pullie
sorry,I know,I need to grow up
