I'm curious how you manage ATM puts? Yes the theta is very high but your delta to start is .5, so if market trends against you it will go ITM and your theta disappears?
Let's use real life examples. The July ES is at 2040. The July ATM straddle can be sold for 95 handles. The theta disappears (as you put it) maybe if we get a 150 handle move against you which we have have one or two of in the last two years. You "want" the delta to go to one. Why? Because when the delta goes to one and gamma goes to zero, the hedge is easy and clean, you lock in the loss and move on. There is no panic buying and selling and taking off hedges and getting margin calls. If and when the big move happens, you take the loss, lock it in and move on. All the other months pay off 10 to 20 times the amount the 5 delta puts pay off. Again this can be shown quite clearly using excel and if I have some time this weekend I'll build an excel sheet showing the p&l distribution. Trust me, the upside is 10x.
Now this does not mean this a risk free strategy or free money, it simply shows the degree of how bad selling 5 delta puts are. it's a relative comparison. It's much cleaner and involves much less stress. If I'm getting paid 5k per one lot on a straddle vs selling 20 lots to make $200, the difference in stress is night and day. You won't enjoy the margin call you get when those 20 lots start generating gamma and you are running out of margin in your IB account. They have fun ways to close these positions.
