Should I avoid selling TLT/TMF 9/20 puts?

I sell CSPs. I know Fed’s meeting is mid week next week and I wonder if I should wait until after the meeting to sell more options on TLT/TMF because of the potential large price swings after Fed’s decision.

If I do want to initiate a trade now what do you think is a relatively “safe” strike price for 9/20? Thanks.
