I too miss the 'screaming reach'. My last two boats were N6.0na, and P18-2. Both of which were excellent on a reach, huge jib and all.
OK, so you don't have to tack or jibe (usually) on the reach. So what? It still makes it more fun IMHO.
In fact, since the B can can offset of A, or C, why not offset it off of A, so then a chute boat could possibly sail one tack to C? Yes, this does take the tactics of jibing out, but still a good suggestion.
