Reddit mentions of BILTIN ABEC-7 BEARINGS single set

I have two questions:

1. I want to get the square tail from Churchill (it is #13 on the page) (28 in. long, 8 in. wide, and 14 in. wheelbase). What is a good truck size for a board that size? I was thinking about the Caliber Blackout 9", but I don't know how that would fit with the board because this will be the first time I am building a board.
   
   
2. Are there any major differences between the Biltin Abec 7s and the Zealous Built-ins? They look pretty similar to me, so I was thinking of getting the Zealous Built-ins because they are cheaper. Opinions?
   
   Thanks
