Crown of glory - Straight or Curls?

Been very faithful keeping my dark long hair for years & I guess it's time to change?!? Thought of getting a wavy perm but there are 101 types of curls in the market and I just can't decide....

A wrong decision will caused me to...

1) Taking "false" 2 months maternity leave (slim chances)

2) Having bad hair days for the next 6 months

3) Need to cancel all my MPO performances? :p

4) Buy a wig

Sigh...decisions...decisions...decisions...
