To paraphrase Article 80...inspectors rule & electricians drool. In 20 years I've only had one seriously unqualified inspector. I did what he wanted, charged the customer (who refused to pay), liened the property, customer went bankrupt, I lost my lien & about $1,000. Enough people complained about the inspector that his contract wasn't renewed. Otherwise, sometimes I know more about the code & sometimes the inspector does. If they do, I'm glad to learn more & if I know more I don't throw it in their face.
A small consideration not mentioned in the code is that my payment usually depends on passing the inspection. It's always been easier to do what the inspector wants than argue. Even if you're right it could come back to bite you...say there's a rule about the distance between the meter & the panel and you are 1" over. An inspector could make you pull the meter socket & install a disconnect type. Sound expensive & time consuming? It's always a good idea to call the department with questions before the installation. Sometimes I call & ask what code they're on, & what they look for in grounding. Sometimes after a couple questions they'll let you know specifically what they look for.
On your question, you do have to allow for some slack in the overhead span. On one occasion the POCO put so much slack in the wires that it created a violation. I called & asked them to tighten it up a bit. It sounds like you made it a little too close. There are a variety of supports available to raise the point of attachment.
