Rather than thinking in terms of an iron condor, you might examine whether to trade matched-margin vertical spreads on each side of the market. When the market tanks, write the bottom. When the market spikes, write the top. You'll end up with an UC, but with much better positioning. (And, better sleep.)
when you do that you're essentially trend trading though, calling the bottom when you write the put spread and the top when you write the call spread. you'd also take in less on the call side assuming vol comes in as price comes up to where you want to write the spread. if you're that good at calling tops and bottoms there's much better ways to make money
