Lonny,
Any pressure from about 12 up works on the Husky. I think 18 is a pretty good compromise, but if you are mostly on pavement, you may want to run more like 25 to manage wear better.
Bear in mind that running fairly low pressure requires that you monitor tire pressure pretty regularly. Most tires and tubes pass some air through the rubber compound, thus lose some pressure over time. Also, if you go from warm to cold and your warm pressure is 18, when you get to the cold temps (as in rolling out of a warm hangar in winter) the tire pressure will drop substantially.
None of this is a huge deal, but if you allow the pressure to decrease below about 8 or so, you are pretty likely to slip a tire, and possibly cut the valve stem. That can get ugly, and at best is a serious pain in the butt.
On pavement, I'd keep the pressures up just a bit, like at 25. On mostly gravel, off airport or grass, 18 works fine. Also, bear in mind that higher pressure makes the plane easier to move around by hand on the ground.
