Colyn,

Where do you live? I live in the Detroit area and fly all winter long.

My last 3 flights to North Carolina had ice above me and south. I had  
to fly north 30 miles, climb above it and then head on south.

I am stopped once or twice a year but not much more. I don't touch  
ice with my plane. Even a very slight "frost" on the leading edge  
slows the plane about 30 knots.

My last plane was a C-340 with known icing. I had it for 2 years flew  
winter and summer and maybe once saw ice.

I wish that I had deice equipment but if I put any more equipment on  
the plane, I don't think that it could get off the ground. I just  
landed in NC and took off at 1,900 lbs. Very heavy for a LNC2.  
Compromises, compromises.
