I know that Herm Perez, and Jim Ives have been using a dry air purge thru a Drierite
drying unit successfully with hypered TP.

I've been using only hypered Royal Gold 200,  and LE400 the last couple seasons,
without any purge. I figgered on giving it a try with the dry air purge before
lugging along one of my nitrogen tanks. The nitrogen tanks are just a bit too much
hassle!

Thanks again--steve.
