I don't feel cheated if I don't use every club in my bag.
As long as the shots on the course are of a sufficient variety, that is all that I ask. I might use my 5 iron on approach several times a round, but it might be uphill, downhill, side lie, whatever. Courses with a natural rolling topography help to break the monotony if you end up using the same approach clubs every hole or two.
Frankly, with my game, I might use most clubs or just a few on any given day anyhow, I get into trouble on the course more than I am willing to admit.
A couple years ago, I did drop from 14 clubs to carrying 10 or 11 standard, I found that my 4, 6, and 8 irons were pretty shiny, as I tend to always use the odd numbered irons for some unusual reason. Combined with my Sunday Bag it makes for a nice and easy walk.
