Excellent point John thanks ,-agree <br> <br>-This is just a quick rehash of the existing iF RULES , why they wanted a constant section is due to their efforts to control costs and expensive aspects . <br> We need to reorganize all aspects of the rule and review each catagory with some expert advice by people with current practical experience in that particular area --{carbon mast builders }--Do you have current costs on C F masts in radius section . <br> thanks much ,-all info is greatly appreciated . <br><br>
