Senior flex - typically, it's tough for those with senior flex to get enough height/carry with a 3 wd unless it's use is as a second driver. I'd look at a 5 wd, forget the 4i, get a high launching 4H. BUT start playing and see how the bag works - if the 4 and 5i are not getting enough height and consistency, consider hybrids or even a 7 or 9 wd. As to the LW, depends on your short game, wedge fitting and technique. Most ams play too little bounce in their wedges - get fit after more work on the swing. Good luck!
