ORLANDO, Fla.-- With apologies to The Hollies, it ain't heavy, it's my driver.

The leading contender so far at the PGA Merchandise Show for the Most Surprising New Club is the Heavy Driver, brought to you by the folks at Boccieri Golf who created the popular Heavy Putter and followed it with last year's Heavy Wedge.

This year, after positive reactions to the wedge, Boccieri came to the show with the whole rest of the set, uh, heavy-ized. The driver. The fairway woods. The hybrid. The irons. And you know what? They were hot. I was among a long line of startled golfers who tried out the driver on the range at Orange County National during PGA Demo Day and, after busting long straight drive after long straight drive, stood there with mouth agape and said, Holy cow. Or expletives in a similar vein.

The ball had that wonderful feel that golfers love of just jumping off the driver's face. The clubs are somewhat counter intuitive. They are heavier but the secret, says founder Steve Boccieri, is that they are balanced. The driver's head weighs 208 grams, but by adding 50 grams to the butt end of the grip, the club is better balanced and suddenly a very manageable swing weight of B-6.

ORLANDO, Fla. — Pick up one of Stephen Boccieri's putters, and you know right away that it's different from everything else on the rack. Tipping the scales at about 900 grams (nearly twice the weight of most putters), his original invention, the Heavy Putter, is the Hummer of flatsticks.

But like SUVs, even Heavy Putters are getting smaller these days. Here at the PGA Show, Boccieri is begrudgingly launching a new Mid-Weight family of putters, which tip the scales at 750 grams.

"For a lot of people, it was too much of a quantum leap to go from a conventional putter at 500 grams to jump into one of our putters that was twice the weight," he said Wednesday. "We couldn't overcome it. People would literally pick it up and put it down."

The new Mid-Weight line is designed as a compromise, giving golfers who are looking for a heavier putter an option that doesn't feel too cumbersome. Unlike previous designs that featured circular cutouts and weight inserts in the head, each of the six Mid-Weights is either a classic blade or simple mallet design in either a satin or black PVD finish.

The Mid-Weight Heavy Putters are all made from stainless steel, have 3°of loft and are available in lengths from 32" to 37" for $169.
