I had a situation in a game where I popped Descent of Angels for Capt. Smash after Wings of Firing him. I needed a 9 on 3D6. The entire game hinged on making this charge.
I rolled a 5, 1, 1. I then had to decide whether to CP Reroll one of the 1s, which I would then need a 3+, or reroll the entire 3D6 because of the Angel's Wing. I ended up using a CP reroll, stuck the 3+ and made the charge, but I wish I had known the following:
On 3D6, you have a 74.07% chance to roll 9 or more. So, if you fail your 3D6 9" charge, if a single CP reroll would mean you only need to stick a 2+, then your best odds are to reroll that one die and hope for the 83.33% chance of making that. (And it will cost you a valuable CP).
However if the single reroll will need a 3+ (66.66%) chance or worse, then you are much better off picking up all 3D6 and rolling again (provided you have access to reroll failed charges, such as from the Angel's Wing or Lemartes).
Below is the probability table for 3D6
