Thanks Tim,

I was also adviced to avoid radials crossing if they are not insulated. 
Well, at the end the difference is small if any, that's true.

So as I have insulated wire, I will maybe put still all the radials in full 
lenght (option 2), it seems easier and I also have more wire down on the 
ground then:)

Look for ES5RR this weekend from my station. Toivo will be running SOAB.
