DC300 Maybe this is where people get the idea they hit it 280-300 yards "when I hit it good"?
I would imagine so.
Although the L/M does save a lot of time gathering some data ( provided the condition of the launch was set up correctly ). I always favor the on course fitting , The method of seeing the ball flight and pace off the distance is more reliable IMO.
I once played with a guy traveling from Chicago, he looked at the yardage on the score card and decided to play from the tip. I asked him if he wish to play the 7,000 yards in Winter condition, cold temperature windy and damp turf... he got angry and replied " I'm a good golfer you know ". Okay, so off we go. He did not refuse when I suggested to move up to the middle tee boxes after a few holes.
Mine issue relating to golf is, each week is a different adventure. Some days I feel fine for my age and some days my shoulders hurt and could not raise the right arm above the shoulder and could not extend the arm to reach out for things. Some days my feet hurts........... So if I fit the golf club to my liking one day , which will not guarantee it'll be the right fit the next day... LOL.
That's why I have sets of golf clubs with all different set up. Flex from X to R, Steel shafts to graphite and irons varied several degrees in lie angle...... Just have to learn to take the right set out to the course in any particular day. Maybe one set for the front nine and one set for the back nine. Just kidding !
