scotts33 I also think the old adage of aim small miss small also comes into play.
I like this most in fw clubs. The 3 wd. heads of today are just not suited for 'off the turf', the main reason players have trouble doing just that, imo. I've been looking for 2 yrs. for a 3 wd. head that is smaller, but not a "tour" head of 14 or less. I have the Diablo Tour @ 15, but it does not launch nearly high enough to get good use of it.
I do have a short set of the Acer XV Tour Blade irons. Hit them as well as anything, but the heads are not all that smallish. My Taylormade M1 iron heads look smaller.
