I haven't used wood decks at 1/350 or 1/400, but the opportunity hasn't come up. I would just say that you should think, at 1/350, is it accurate? I have modeled at 1/160 railroads for a while, and even at that scale real wood is a challenge; the grain is too big and the color is not something you can scale easily. I tried a number of laser cut kits and went back to painted styrene.
I've tried to do a scale measurement on those wood decks, based on internet photos of the wood piece vs. a best guess of actual plank width based on photos of the ship. Most recently I was looking at a Japanese cruiser, the planks were about 25% wider than the photos showed of the ship. I forget the numbers but I counted both in a picture where one could see the entire beam planked, at a spot that was identifiable .
So 9" becomes 12". Seems trivial but in fact it has a big visual impact.
I personally think a good base color paint and a little bit of careful brushwork on the kit plastic is a better approach.
There's also all the issues of fitting around the surface detail and making up for the thickness.
So I say don't bother.
