Logo Variations for Cash Out Mobile App (Sold)

Some variations developed from a recent logo proposal for a cash out mobile app. The initial version can be seen in the shot I am rebounding, but these are some versions I am considering for use in print and instances the gradients might not work,

What do you guys think? do you use alternate versions for the logos you design, like outlines or single color or do you offer just a greyscale variation for use in print.
