I voted 1, I will continue with the current Zero lineup. So far I have 2 of each of the Zero valks and plan on getting 2 of the 0S and possibly a couple sets of the reactive armor. Not sure if I will get multiples of the CF though, but will wait until the time comes to decide. Out of all of the Arcadia valk I own which is all of them, I have only opened 2 of them and never transformed them lol. I am low on space, but I had to open 1x YF-19 and 1x VF-0D.
