From strictly a loft progression standpoint, the KE4 Tour TC #5 hybrid (25 deg.) and the #4 hybrid (22 deg.) would be perfect. Since the #6 iron in the TS3 is 28, it would give you a nice transition. If you prefer to have more of an iron look in those long irons, you could go with the KE4 Max % iron and have it bent 1 degree weak (from 23 to 24 deg.) and then add the #4 iron KE4 Max at 20 deg. that too would give you a good loft progression with the 4 and 5 Max irons giving you the ultra game playability in the longer irons. So those are two suggestions to complete the iron portion of the set.
For fairways, and I don’t know what you have usually played, I would suggest looking at the #3 (14 deg.) and #5 (18 deg.) KE4 TC fairways. Again, the progressions fit and they are as solid feeling as any fairway’s you will find, in my biased opinion. We also just received our new TC IST adjustable fairways and they might be an option to consider.
Drivers are different. You need the best loft and shaft flex/type combination that optimizes the launch and spin for YOUR swing and speed. Obviously I would suggest you get fit for all the clubs in your bag by a qualified professional fitter, but if you know your game well and know what you like, you should be able to do your research and pick the components that work for your game.
Hope this helps.
