Buggy board for uppababy vista

[Pinkpiglet]

Hello

I am looking for advise on which buggy board to get for my vista. DD is 23 months and DC2 due next month. I have decided against a double as Dd1 hardly ever uses the pushchair.
I am not sure if I should get the Uppababy piggyback board or if the lascal mini/maxi will suffice.
Does anyone have experience of either on the vista?
I also have a baby jogger city mini as our small pushchair. Could I use the Lascal with this?

I use the Uppababy board and DS likes it a lot.
