I’ve played several rounds with these over the past few months.
Pros:
Look great
Thin-ish sole
Great spin
Straight on mis-hits
Cons:
The sound and feel on mis-hits can be weak
Lower trajectory than I expected, this is good in 9-GW, okay in 8, iffy after those.
Distance, at my speeds, I don’t think there’s any gain over a solid iron of the same loft. I think the advantage is more about forgiveness in a tight package.
