The irons could be made of zinc, which would be noted by the much larger hosel diameter (where the shaft is inserted) as zinc does not possess the same strength as stainless steel. It should be noted that not all of the store-line equipment may use these materials. The price of each set will more than like indicate what materials are used. Lastly, the specifications of pro-line clubheads tend to be tighter or more consistent from head-to-head than what you would find in a store-line set as well.

The shafts and grips that are found in pro-line equipment tend to be better quality than store-line clubs. Another way of cutting costs to produce a starter set is to use less expensive materials. The shafts may consist of fiberglass as an additive or as a high percentage of the overall shaft. This tends to make the shafts heavier in weight, not quite as stiff and possess a high torque (or greater amount of twisting). The results are typically a higher ball flight with slightly less accuracy. The grips on store-line clubs may be made from lesser grade of rubber
