Joining horizontal exterior cladding

[JF.]

I need to splice some exterior paneling. I have a router bit set with tongue and groove bits, so my plan is to route the ends and then glue them together, what do you think about that?

Isn't it enough to splice a rule?

Isn't it enough to splice on a rule?

It might be enough, but to avoid gaps in the panel maybe my idea is better?

Then it's just a matter of trying if a regular joint isn't good enough.
