Steve,
I faced this exact problem recently with a client of mine. Why is it some clients feel they know better than a copywriter even though though have no idea? They gradully changed my copy back to the old copy that never pulled.
In the end I asked him to either do it my way with a compromise or I wouldnt do it for them. They would lose their deposit and have to start all over again.
In the end they decided to let me just do it.
You can see the blend of both on this page. Not my usual style but it played to their audience and at the same time did what it had to do ... pulled a result for them.
Check out the demo page here. Please dont send anyone outside this board to this page.
