Reaching by itself is just drag racing: the fastest and the one windward wins, so, to my opinion it is not enough to make a good race. but, a dose of reaching can be good: what about the good old olympic course with three marks(ABCACA)? I like this one: a lot of downwind/upwind plus the mandatory jibe at the B mark which make things very exciting (plus the fact that with a spin you have to deal with wind angles through the B mark: can be pretty difficult if windy). I would like ro races these.
