I've been eyeing up a set of irons on eBay and they come equipped with aldila vs proto 85 x-flex shafts. I've never played graphite iron shafts and just wondering if anyone has tried these and what they might compare to. They were a PGA professionals clubs so I figure they cant be that bad. I'm about a seven handicap, swing a driver about 95-100 mph if that matters. Thanks.
