It’s better to code your own theme from scratch rather than using other frameworks. Later you can use it as framework for your other themes.
I think I asked the wrong question. I’m not actually after a framework as such but rather just a drag and drop page builder. I assumed this was included in frameworks but from looking around there are a few decent plugins I have found that could be quite user friendly.
I had a look at the Site Origin builder. That looks quite nice actually. Will look at the Aqua one now
