Ggs! 1 tip I got watching jamcowl is that the smoke restock timer is faster than the stim timer so you hold one smoke and let it almost restock then swap it out for 1 stim for faster stim farming .. hope this helps .. I have a video showing this in my uploads
If you run smokes and stims you can use the smoke restock timer to farm stims faster and smokes help you escape when being shot at too .. I did a video on farming stims with smokes a few days ago
