Reef points, we did without. If one has a good backstay system for de-powering and a well cut sail, we thought for the lulls and off wind sailing, a full main was important. We did have a flattening reef put in, but never have used even that. If it starts blowing that hard during a race, I doubt that we could reef underway without moving way back in the fleet.
Windows are great on the main and jib both.
I like wool yarn for tell tales, on the top two battens on the main, and three short ones end to end on each side of the jib starting about six inches back. Tie stop knots close to the sail on each side and waa-laa, no problems. Keep them away from seams as they will hang up on rough edges. We had very little weather helm with that configuration, and I guessed that that was part of the reason we could move so fast. But . . . that's another story.
