full port ball valve brand selection

another question, since my manifold's lines will be coming from below (crawlspace) to the copper manifold all the branches facing down, my main feed line will be just one of the many lines.

The copper manifold has 1" trunk and 3/4" branches. My main feed is 3/4" in the middle. Then each branch is either 3/4" or 1/2". Like below.



I will have a ball valve 3/4 or 1/2 on each line. What I just realized is, if I put a valve on the main feed line going into the manifold, and a valve on each branch coming out of the manifold, I may have to orient the valve in opposite directions, correct?

I think most ball valves have no directionality, there isn't an arrow on the body on the brass ball valves I have used in the past so most likely I can orient them however I want. But in my case, if I have say 10 ball valves, the feed is going into the manifold, the other 9 are coming out. If I choose to orient the valves a certain way, in other words, designate an upstream end and a downstream end, I will end up having the handle of the feed valve turn in the reverse direction of the other 9. This is not necessarily a problem right just a preference? I see several options.

(1) Decide on an upstream end and downstream end for the valves, and the feed valve will just have the handle swing in an opposite direction, that's fine, no issue.
(2) Flip the valve for the feed, it has no direction anyways, make them all look the same and turn in the same direction.
(3) Why even have a valve for the feed? I have a valve 40' upstream of it where it enters the house. So a valve there is sufficient as there is no branch between upstream valve where it enters the house and the downstream end where it connects to the manifold, unless a leak develops along that 40' line that helps isolate it.

Which way will you go and why? Or is there an option I haven't considered.
