Ive hit the f9 one length and regular f9 irons and like them quite a bit. The cavity and sole are gawdy as hell but they look good from address. Once u get to the middle and long irons the flange can be seen from address, which imo not a big deal. Super easy to hit, felt good, were forgiving, a lot to like. Just not a fan of the stock/demo shaft offerings way too light for me, but if they fit you then by all means. Also pay attention to the specs on these, strong lofts, which is nothing new, but also upright lie angles. If u order new from cobra you will have quite a few shaft options at no upcharge, same for grip, lie angle and length adjustment at no charge.
