Rifle Shafts

Is there a clear advantage of Dynamic Gold S-300 (stiff) steel shafts in my irons?

I am looking for a set of Callaway X-18 irons eBay, and I wanted to know if the axes are nothing special. I'm not sure what comes from the factory, which is "secondary market" etc. I heard rifle tree, etc. Maybe someone can put into perspective for me. It would be great!

Dynamic Gold shafts are probably the most consistent clubs All other steel shafts together. Little more difficult than average (as determined by the head speed, not effort), eligible axle rigid and therefore less flexible and faster than the axis R. Or, if you use axes that are over 1 inch longer than standard, you may require a rigid shaft. Short and several trees flex. Go into a store and get a good speed of his head with an axis of measurement comparable to contemplate using it. It is the most reliable indicator flex you need. Graphite shafts are generally lighter than steel, but not necessarily more flexible. They come in a number of rigidities, along with steel shafts. The weight reduction can often speed head or more axes, without taking weight, and therefore require a rigid axle of a comparable steel shaft.
