A 35 lb youth or light-recurve draw at a 27 inch arrow flexes the shaft very little, so it takes a weak 600 spine. Fitting a stiffer shaft here would leave the arrow flying poorly off the shelf.
Spine is a starting point, not a guarantee, because a 340 from one brand can differ from another. Confirm on your arrow maker's chart at 27 inches and 35 pounds, or bare-shaft test before cutting a dozen.
Whatever spine you land on, keep the finished arrow at or above 175 grains total, the 5-grains-per-pound floor, so the bow is not shooting dangerously light.
