Spin off of mats vs grass, what is the technical cause?
There have been a few common ideas as to why this happens but is there anyone in the "know" as far as what the actual mechanism is?<br />
These are the ones I have heard, some I am more inclined to believe as plausible than others.<br />
1) The club tends to dip under the ball because of the squishy mat and the ball catches higher on the face producing less spin and higher launch angle.<br />
2) The golfer's subconscious changes their swing in anticipation of what is often times a harsher impact with the turf after striking the ball and this causes the strike change that creates less spin.<br />
3) The turf causes MORE friction with the ball so it slides up the face more and doesn't spin as much as a lower friction grass lie. (This theory I gravitate towards the most).<br />
4) The turf is soft and doesn't allow the ball to be "compressed" as much as on grass, so it produces a lower spin loftier flight.<br />
These are the ones I see the most. If you have another common cause you have seen floating around please share. I would love to get to the bottom of this as I have an i door sim I use and this also relates heavily to club fitting so it can effect quite a few people.<br />
What are you thoughts? Had anyone tested this and know the true reason it happens?<br />
Edit: I have seen a few tests on the internet regarding this but nobody seems to have come to a real conclusion, they just show that there is indeed a rather large difference at times.
