if you can stomach the low key count I’d highly recommend something like the Sweep. if built wireless it becomes an even better travel board IMO but it’s not a necessity. Also sometimes uni-bodies can make good travel boards as they work pretty nicely on your lap or other awkward situations a little better than a split. Personally I have an Osprette which I love.
The others you’ve listed are all good options too. Good luck.
Even better would be to use git submodules for them rather than copying the into your tree.
