I would be very scared to cut that early, Jamie. The earliest I've cut is Day 50. I've not had any eggs that I've let naturally pip, one - because like you, I've get the fever to cut, but more importantly (to ME personally) is that I had the opportunity when I visited NERD to see examples of two eggs that the babies were unsuccessful at pipping their eggs, and you could see where they stripped all the blood vessels off the top if the egg in their attempt to pip their eggs, and ended up drowning in their eggs. So it worries me that if I don't cut, that I could potentially lose a baby.

I've got a clutch that will be Day 52 tomorrow that I'm considering letting pip on their own just to get that experience, but knowing me, I'll probably give in to the scissors!
