LOL I don't know about putting it in such strong terms, but yeah: the advantage of a trike is in how SLOW it can go. If you want speed, get a 2-wheeler.
If you're set on a trike, and in particular a tadpole, then you want the stiffest boom you can find on a light frame. Those two items are sort of mutually-exclusive. The new Bacchetta/Carbontrikes might be the ticket; but I at least wouldn't be willing to pony up the $6K on a "maybe."
