We have tried other Multipurpose paper for our printer and it just doesn't come up to the stardard you have set. We like the weight and the brightness. Best of all we like the price especially when there are rebates!
This is the only paper that I have purchased that has a major paper curl problem. I don't know why since it is being used in a standard laser printer setup. Paper curl prevents you from collating sorting etc. and is a bummer.
