IMO, it doesn't often make sense to short the backspread (1x2) in lieu of the fly, as the deep OTM wing is usually cheap ($-terms). Obviously not the case on index with the wing being a DOTM put.
Yeah I guess you are putting that far OTM wing just to avoid the nakedness. I used to dabble in ratio spreads but I guess it never suited me to be honest. Not like short straddles are any safer haha.
