Interesting comments. Thank you all.
As I've got older and the distance I hit the ball has got less I find it's fairway woods and hybrids that are now used most. As has been mentioned above, this probably means I should be moving up a tee or so. The hassle is, when playing in competitions, all have to play from the same tees, and these are usually towards the back. Okay there are senior comps but they are not necessarily held at times and frequencies appropriate for all.
Having to hit more fairway woods and hydrids, including on par-3's (sometimes a Driver now on par-3's) means missing more greens in regulation than in previous years when approach shots with mid/short irons were perhaps more the norm, which then increases the need to use wedges or chipping clubs around the greens. In many ways, apart from chipping and the like I hardly ever seem to use 6-7-8-9 irons.
