Thanks for the replies guys,
Re the 3/4 22mm, I had assumed you couldn't get 3/4 x 15mm so it had to be 22mm, but ive since found that you can get them, this is taken from the installation instructions of my valve
I had though the hot and cold feed had to be 22m as they are G3/4.
So straight compressions it will be for attachment to the valve itself, thats decided. Just need to decide on whether to bend the 90 angles now or just go with the yorkshire solder ring fittings throughout with yorkshire 90 joints....
