You may find these interesting;
200TT instructors...
200TT IFR pilots
And some peoples views on the choice between the two:
Choosing between IFR or Instructor ratings
And there others
Me personally, I opted for the IFR, I figured I'd need it at some stage. (As it turned out, at around 400 hrs TT) Plus I had the view that, who was I with 170TT to be teaching others to fly, AND after trying to teach the ex to drive, well, thats a long story...
Good luck!
