Combining two 8" ducts

Hello, if combining two 8" ducts should I use a 8x8x10 wye or a 8x8x12 wye? Thinking the 10" wye even though it'll be slight less cfm than the combined cfm of two 8s

I'm upgrading ducting and looking to combining two supplies that are in one room.

Also two returns, and 8" in one bedroom and another 8" in a bedroom, across the hall.

Thanks!
