I would go 5 clubs in my smallest carry bag. Hybrid,7i,9i,sw,putter. No par 3 courses in my area so never get to do it, but im only using 6 clubs in total on full length courses and it seems to me i'm just a tad more consistent with half a set of clubs,just the ones I hit best and I have went from shooting 45 for 9 to more like 42 so less clubs has meant 3 less strokes per 9 holes. My handicap dosen't always reflect it because my home course has a low rating because it's short but it is par 72. I played a very long course early this year with only a half set and played better than normal so it can help certain players.
