Based on your choices stated, if it were myself and there was only one option it would be the XX for the additional coverage and for the look of 'fuller orbitals'. It's a Juliet - Amplified!
A small or small medium head would be better suited to a penny or indeed the much criticised half X, medium to large would be a Juliet but as I have a large head and if I had the choice of the full series, it would be a Romeo 1.
