Clones generally are trying to make a quick buck by creating some lookalike heads - some of the proprietary technology just isn't there in clones (such as weight distribution, aerodynamics, and in putters, insert materials).

Example: I have both a 2ball clone and an actual 2ball. The clone is much heavier, and the insert is not the same as the Odyssey White Hot. But it sure LOOKS like an Odyssey!

That said, when it comes to irons, I would buy clone heads (ok, I did buy clone heads, and assembled them myself), and get them built by a respectable clubmaker. There's not too much technology going into irons, per se, (yes, weighting, but there's not much to do for irons, IMHO). In fact, my brother-in-law bought some Pinemeadow clone irons, and loved them. We pulled and spined the shafts, and now he loves them even more.

But generally speaking the best performing, best value clubs are component (SMT, SnakeEyes, Dynacraft, LogicTech, Maltby, etc). They're developped like OEMS, but without the big price. And for those that want to play Tour equipment, we're starting to see more and more pro's using components (Voodoo Putters, Yes! Putters, SMT drivers).

As for custom fitting, it's well worth it. Even if you're average height (so clubs aren't adjusted for lie or length) it quite important to have shafts that fit your swing. Too stiff, and you'll never load them properly (and may lose balls right), too flexible, and you'll overload the shaft and spray balls everywhere. And don't be fooled by the letters. One companies' 'R' flex is another companies' 'S' flex, and a thirds' 'A' flex.

A new highlight: Golfing the home course on Christmas Day.

I say it too often: If it's golf club shaped, you can play with it.

For the record, I'm a club doctor, not a swing doctor.
