Mono / Mixer Tap Tails Internal Bore

I'm fitting a mono/mixer tap to a basin. Its a low pressure system and they are low pressure taps. They have been supplied with copper tails, 12mm thread on the tap end (I think!) and 15mm the other end.
The tails dont reach so I would like to get some flexis, but I want to keep the flow as good as possible.

I cant seem to find any flexi tails with an internal bore of 10 or 12mm that are suitable for a mixer tap. And I really dont want to restrict the flow down to 8mm.

Is there any difference between tails sold for mixers and the normal ones?
And if I bought them would I find they wont fit?
What is the difference?

Any suggestions please?

Thank you.

They are about 2" too short. And one is on the wrong angle. And they are going straight onto compression isolating valves.

I cant think what kind of joint would flex enough in such a short distance and would join a 15mm copper tail to a compression valve.
I just thought a 30cm flexi would do the trick if the internal bore was 10mm.
I think I might just try the 8mmm bore flexi tails and see how good the flow is. They cost less than £5. Then if they dont work well enough I will try something else.

I would still like to know the difference between mono tails and ordinary flexi tails though.
