Chip strategy for remainder of the season?

Seems like most people went for either TC or Ass man this GW. I personally had locked in the TC before DGW25 was announced, though looking back I believe ass man may have been the better chip to use this week.

Nevertheless, those of us with all the other chips still remaining (WC, FH, BB and Ass Man for me), what sort of time line are you going for?
