Hi Vanyar and welcome,
The ladies have provided some great suggestions above. To answer your question Ammo is the better of those two for your purposes.
In addition to these, depending on your style, what women you are targeting, and what kind of wingmen you are rolling with, you may want to consider:
Instant Jerk - can be handy with attracting the 9’s and 10’s
A314 - helps with status especially when you’re rolling with dominant types like Style, Mystery, Tyler etc.
I suggest you read about all of these in The Mens Guide Let us know if you have any questions and be sure to return and let us know about your results
