Ok guys i maybe be able to offer you some answers here about the deviations/vem in this game. What i have noticed for the past few weeks and also in this thread is the number off complaints about the game are coming from the majority off people using either "the starter set" or " the "rapture set".
The rapture set & starter set have a lower precision rating than, for example, the Ping G10 Masters.
Lower precision means the ball will fly off the club face with less
consistency/accuracy. However, it's high forgiveness will 1) slow down
the meter, and 2) reduce the severity of miss hits (i.e. keep you on
the fairway).
Overall... that set of Irons is more of a "game improvement" set of clubs vs. a performance/precision set of clubs.
So the answer to all our questions over the last few weeks is that the deviations/vem seems to be implimented within the precision off the clubs. So the higher the precision off the club the less likely you will get deviations/vem.
This answer has come from a very good source by the way, so we now know where in the problem lies, IT IS IN THE PRECISION OFF THE CLUBS. Hope this helps !
