I'm going with the netting sewn into my ZPacks shaped tarp (Hexamid) now, the Borah Gear bivy takes too long to get into and if a midnight call comes in, too much hassle to get out of then. The added netting will only weigh less than an oz. over what the bivy weighted which is for sale and I'll have all that space inside my shelter to change clothes, eat read.
