Pros: accurate and consistant
I've played Callaway X16,X20,Ping Eye,Eye2,Eye2+,Zing,ISI,and i5 and until I bought a set of these used off ebay I never was really comfortable with my iron play.Since playing these my distance on any given iron is much more consistant.Along with that comes more accuracy as well. I'm now flag hunting where I used to be pleased just to get on the green.For me I can say they have truely improved my iron play.
How Titlest describes them"The oversize long irons feature enhanced offset for a higher, straighter flight, while the traditional short irons are designed for shot control and greater playability into and around the greens."about sums it up for me.
