I did - with "coaching" from Kara, one of my dear friends and mentors. I also had the benefit of having visited with Kevin and Kara about a month before my first clutch was due to hatch and got a hands on lesson from Kevin on his methods and tips.
I chose cutting for two reasons. The first is impatience to see what is in the eggs.
The second was seeing first hand a baby ball python that drowned in the egg when it was unable to slit its egg (also part of my lesson from the Evil Morph God).
Is that a rare occurance? From what I understand, yes. But enough of a chance that I'd rather not leave it to chance.
Day 52 is really the earliest you should consider cutting, may people wait until Day 55 or 56.
When cutting Day 52, it took about 5 days for all the babies to fully come out of their eggs. In the meantime, I misted them daily to keep the yolk moistened and not dried out.
