The only thing I don't get with the whole leathal theory is why are there not a lot of bad eggs with spider x spider pairings? I am sure NERD has done tons of Spider combo x spider combo clutches by now to make some of the crazy combos he makes. Unless he is just not reporting any egg death issues I don't see how this theory can hold up. The egg would not get the second spider gene until ovulation. That would mean something would have to come out of the female. Either a bad egg, or a good egg that goes bad during incubation. The point is that there would be evidence of an issue. So far I have not heard of a single person with proof of any leathality issues. The whole thing started from one persons conjecture and that is all it takes in this hobby. Same thing with the caramel females can't lay eggs thing.
