air compressor plumbing

I don't think that I've seen a v style before.
But depends on source compressor and how many CFM it is capable of putting out at a given pressure, that 6CFM difference may be moot.
It doesn't hurt a bit to go oversized on piping, regulators, fittings etc.... Up til where the bigger fittings become clumsy to use .... A lot of times you can't get the tools rated CFM to reach the tool with dinky fittings. Which is why you have to crank up the pressure to (somewhat) compensate for too-low flow
Those 1/4" coily hoses may be convenient but for flow they are the worst
