So I think that we have established that, if nothing else, there is a huge variation in the distance people can hit the ball.
That's not really surprising as I doubt any two people have identical builds and swings (not to mention the courses that they play).
DMD's have changed the reality of distance claims. It's often a bit disheartening to find that you are actually hitting your best shots 10% less then you had thought. Having said all that, as has been pointed out on numerous occasions, it's the score on the card that matters, not the individual shots.
The tour pros always play a hole backwards. They want to be hitting their approach shot from their preferred distance, position and club. Too many of us are guilty of trying to whack it as far as we can off the tee when we should probably be thinking of positional play first. I hit most of my irons really well when I can take a full shot, but my percentages drop when I need to finesse a shot (largely due to lack of practice). Therefore, playing my second shot from 75 yards is not as likely to produce a result as from 100. Sounds perverse but that's the strengths and weaknesses of my current game.
Equally, a well designed course has traps placed for those that don't utilise good course management. I've often played with guys who see a line of bunkers at 220 yards as a challenge. Because they are fixating on the bunkers it's amazing how often they stick their ball straight in them (assuming they didn't spray it out to the right whilst trying to smash it).
These days I take a mix of Driver, 3 wood, 21 deg Mizuno MP hydrid, and even 4 irons off the tee to try and make sure that I have a good chance with my 2nd. My mid irons are the best part of my game so I might as well try and give them a chance off the fairway.
I can hit the ball a long way when I catch it right. I'm one of those chaps who likes hitting balls over the back netting at the range. However I don't do it often as the necessary coil puts a huge amount of strain on my lower back and I don't do the conditioning work required to do this safely.
I did once put the ball on the front of the green at the 18th at Cleeve Hill. 378 yards tee to centre of the green, but downhill all the way, wind howling behind me and a hard summer fairway. Naturally I three putted!
