Equally blown out here...
Since an AL head would be hard-coated the same as the can, corrosion shouldn't be much of a problem. The biggest advantage of the acetal head is that it is easily machined. the biggest disadvantage is that it _may be_ slightly less durable.
The moisture pads are made from the same material as PackTowels - the light-weight, highly absorbant camping towels. it absorbs 8x it's weight in water while being thin and light. It is much more efficient than cellulose sponge material, is easy to wash/wring out and dries very quickly.

Hi Tim,
Thanks for the info. I'm hoping it settles down tomorrow so that we can get wet here in NE! As per head durability I wonder if anyone has ever hit an obstruction during penetration. On a picky note I see a mini-shroud as a useful accessory for head and hose protection, or is this a non-issue since the Meg. profile doesn't seem as large as a Insp. or certainly as out there as the megacephalic Optima.
