I might be a little late to the party but we print all our models with PVA supports, mostly demo parts of thin 0.7mm grilles.
I have never had problems with it clogging but it is stored in boxes similar to these:

The only difference is instead of sealing the box the heater is placed underneath it, the bottom then filled with desiccant beads and the spools placed on top. I don't close the lid but just place it on top. This keeps my spools at around 25% humidity and I have no problems printing. I should add that the room we print in is kept at 18C.
Previously it was kept in a cool warehouse and we would have to repeatedly dry it.
If I hear any popping ( a sign of moisture in the filament) usually caused because it's been on the machine too long, I pop it in a halogen oven for 2 hours at 60C. Drys up and prints great.

I haven't found it ever prints particularly pretty. But the quality of the actual print is often very good.
