I second the Chris Rock Video! As far as transitioning for 4 months and then chopping, I say go for it but realize that your hair will be about and inch long (if that) when it's in a dry state. I waited 5 months and chopped mine off...and I was in shock and had very little styling options...so accessories are key!
I see that you're not a fan of long-term transitioning...but if you're not comfortable with your hair being super short, you might want to consider braids or kinky twists to grow it out a bit before chopping. Just be sure to care for your edges while in those types of styles. I hope that helps!
