I would say "not good for this project" for the reason that without rings the connectors would fall out.
It wouldn't be impossible to use, but it would be exceptionally frustrating. You would end up fighting keeping the parts in place mechanically, fighting making connections.
Give yourself the best bet for success and use the board illustrated. Then do the other things in that blog, such as really cleaning the copper well, using electrical flux (such as the flux pen), tinning your connections, etc.
