Diago fly + 1 long call or put depends on direction, my favorite: least margin and commissions. Adjustment: sell bull put if went up short strike below the center of diago fly (where 2 initial shorts sold), will flatten more the graph and get out with a scratch. Execution, long the diago fly then long the call immediately after.
If you are bullish and want to reverse this setup, IV decrease will play against you if underlying goes up. When bullish then go straight fly not diago the IV crunch will play with you not against you.
