1 and 2 irons tend to be better players clubs - so tour trends are usually a good indicator of which way we need to go.
Previously a lot of our tour players were using Comp EZ 1/2 irons with their sets.
Now we've introduced the Fli-Hi, all have chosen that over an MX-20 style 1/2 iron.
We felt that if the tour players were choosing the Fli-Hi for ease of use, there wasn't a good golfing reason to recommend traditional 1 or 2 irons to amateurs.
