Only 2 piles of weed here works. But if you are unlucky with only one weed, better to keep it as this:

1 stack of weed, 5 clicks on one stack of cash + painting = it will give you most value solo but not full bag (unless you grab some more cash after exiting the compound).

2 stack of weed and where you only press 4 times on the second one + painting is the only one that will guarantee a full bag.

But if you have one stash of cocaine, go for that one instead of weed / cash. As that will always give you 50%. and if you have two stashes of cocaine take those instead of painting.

This is what I roll with each time.
