The manufacturers of clubs make very high quality products that exhibit the latest in dazzle. An experienced clubmaker has access to all of the high technology that Wilson, Spalding, Lynx, Callaway and Ping have to offer. Actually, an independent clubmaker has access to more technology than any one of the big manufacturers. Clones are copies of original equipment by definition. They are often illegal copies of original equipment.
Clones have another problem.
They are usually bad copies. A proper set of clubs will have a constant progression through the set in terms of lie, loft and weight. If this is not the case, then a set of clubs with a consistent response and feel can not built. Clubs fit just to you and for you. Unlimited selection and choices.
