Fast Hitch is a very good card. An Unexpected Courage for one resource is bonkers, but then Hobbits were never really worth those extra actions; unless your running a super Bilbo or Sam deck. The recent influx of Hobbit cards in the Mountain of Fire has made this even more useful. Another point is that it attaches to a character not just to heroes.

Hobbits don't have very high stats, but look at it this way... There's no hero in the game that wouldn't be worth 1 resource if they were an ally. Putting this on a hero is somewhat like paying 1 for a slightly overstatted ally, plus the extra "abuse ceiling" if you were to start using attachments and tricks with them. Also notice that it isn't restricted. There's really no downside if you happen to be using hobbits and books.

That said, the best recipients are characters with exhaust abilities or decent attack - willpower only matters once per round typically, and hobbit blockers will quickly end up as chunky salsa. That basically implies Merry, in either his or variations. Merry is the only hobbit who can have a respectable base attack, plus you'd have access to Dagger of Westernesse already. Merry could quest for 2 without giving up his ability, plus he could reduce threat multiple times if shadow effects reveal extra cards (fairly common.) Frodo Baggins is another decent target for his 2 and safe block, but only once per round. In other cases so far, it's not too exciting until you get some combos together.
