It has got complicated! My preference is for the proven, but the Iskra salesman is very helpful (Segen) unlike my local proven agent.
Having got planning, my near neighbour has been to see me expressing worries about the position. I feel I have no choice but to accomodate him in the short term (we share the same long track) as I do not want to go ahead and disregard his worries which are mainly about the view! At present the Segen guy is trying to make contact with him to see if he can a talk him round!! The Iskra is more aestetic than the proven. If I cant get agreement now I may ressurect it in about two years. Who knows! All very disapointing.
