Hi Doug
It's probably already been asked, but why are you wanting to expand on the dry (I presume you mean VLM granule) side ? I've had some good, well received and dry-to-walk-on results with it (well, my daughter does it now) but the cleaning depth IMO is not as good as HWE, even with a light pre-spray and low water-delivery rinse which may dry quite rapidly ?
