Well, it arrived and has been tested! (my MD EQL 21 degree).
At the risk of being dull, I can now confirm that
a) it's a good quality thing
b) it goes the same distance as my 3 iron (more or less), with more height
c) my 5 wood will not be consigned to the shed, as this still goes 15 yds further
d) it's easy to hit.
last time I went to the range a boshed 3 irons of the mat for an hour was...um...um....never!
Rated.....9/10.....(can't give it 10 'cause the face is a bit wierd)
