This is not an ideal place to be adding long delta, but my core SPY position's net delta is skewing a touch farther negative than I'd like, so I'm adding in a little long delta with small brush strokes ... .
The other thing is that by doing this, my units on the call side versus the put side become imbalanced, which is something you want to keep an eye on generally. This is because in an oppositional setup like an iron condor, the buying power effect of the entire setup is the same for the widest wing (you basically get the oppositional wing "buying power free"), so having an imbalance in units on the call side versus the put side isn't capital efficient.
Additionally, I'm putting this on in an extremely low volatility environment, so the premium I'm bringing in for the spread isn't great (it's about 43/contract).
But ya gotta do what ya gotta do ... .
