Rope dangling is always worth a go if you might benefit
There is a potential upside and no downside.
There's endless downside - if the rope catches someone who doesn't like to be seen dangling, and is capable of causing grief behind the scenes. The creation of a (very personal) enemy might undo any good you can do for the cause
The best style of negotiation is sometimes to create win-win, not to belittle or browbeat into submission, isn't it?
If I'm completely wrong and shown to be an idiot it's fine, you get used to it after a while 
I know you want to do good for your area (and I'd be doing the same if I hadn't selected a SFBB area to move into). However, I sometimes read your arguments and think that you have indeed shown that.
I really hope that, when dealing with the council, BDUK, and Openreach, that you come over a little different to the way I read your posts.
