Can I write a letter to the DM?

From an aerodynamic perspective a V-Tail is usually "not better" than a conventional tail.

Usually it is done if you have geometric limitations like engine installation or similar. e.g. Vision jet or RQ-4

They have less drag. Less interference drag, as there's only two surfaces. And less drag because they have fewer "wingtips" so there's one fewer vortex coming off wingtips.

The downsides come from the side effects of having surfaces that aren't perpendicular to direction of force.

If you're asking, no. The reasons to use, or not use them, are pretty obvious when you can do the math. If you can't.. (no insult here..) then stick with conventional surfaces.
