Ok, I've made a final decision.
100 degree ES 20mm, not barlowed
14mm Delos
Xw10
2x TV Barlow
This will give me 20, 14, 10, 7, 5
The 14 Delos will come first as I feel it will be most useful. If I don't like any of these I will resell and get something else in the same focal length. Thanks for everyone's help with this. Big decision. I'm sure the collection will not stop there.
