We Love our Clients, And They Love Us

I have been playing with your irons now for almost two years, At age 76, I was a 9 handicapper and climbing. Today at 78, I am a solid 6 from the back trees. The additional distance and accuracy that your irons provide has been a positive contribution to my improvement.

I am not normally a letter writer, but i Felt compelled to tell you. Keep up the good work.


I had been using the Ping Zing with the qraphite shaft and there is an unbelievable difference between your clubs and theirs. It is like night and day. Thank you once again and I have now become your spokesman, encouraging everyone to own these clubs.

Very truly_yours,


Bernard Dorn

It was May 1, 1993 when Bob Chorne gave me a new set of his CBI irons to try. He never gotythe set back; as a matter of fact, I asked him to make me a lob wedge to match. Well, the ’93 golf campaign is over and I must tell you I can’t believe these irons. They’ve taken an old Tour Player like myself, who hasn’t really competed much since
becoming a Head Golf Professional and instantly I played very respectable in local P.G.A. events this year. It has raised my hopes and desires to the point, where I can hardly wait to compete in 1994.

These irons feel great! Their balance and weight is perfect. The leading edge sits and aligns so easily.But, best of all, I added 25 yards
to my short irons, 15 yards to my mid irons, and 10 yards to my long irons game. What a difference I noticed in my iron game this year. A lot less mistakes and alot more birdie opportunities.

First of all, I must thank you. Bob for the opportunity to playthe CBI irons. It is the greatest. Secondly, you say you might have a driver for me that might add 20 to 25 yards. Ch Bob, I can hardly wait.
Thanks again.

Your Head Golf Professional, and friend,

Although I found that the clubes odded distance, the accuracy, feel and trajectory of the CBI irans make them the best golf clut available today in my opinion. Shots hit in the heller on the toe go straight and tend to only lose a minimal amount of distance.

I hond let several of our members as well as several professionals at the clubs and each have gotter great performance no matter what skill level Thank you for making a great yet offordable golf clut.

“I am writing this short testimony to you concerning my feedback from the cb1 tour edition irons which I received about a month ago. I met you at the PGA Show in Orlando, Florida back in January 2022. Since receiving these irons I have played approximately a dozen rounds of golf with them. These might be the most stable golf clubs I have ever hit. Having played on the PGA Tour in the early 1990s and then on the PGA Champions Tour from 2005 thru 2015 I have had access to all the top brands of equipment from all the major manufacturers. With your design of this clubhead and the golf shaft of which you developed as well I can honestly confess these irons are at the top of my list. Being able to work the golf ball both directions and controlling the trajectory is a must to play at the highest level. These irons provide me with a very consistent shot pattern. I’m extremely thankful for having met you and your honesty in presenting your product to me. Looking forward to playing these irons for the rest of my golfing days.”

John Ross
(PGA Professional)

“The CB1 tour model irons are the most stable irons I have ever used. They square up to the target line so easily. Best irons I have ever played. I hit the 7 iron 155 yards and my age is 65. Current handicap is 6 and I hope to get it to a 3 by year’s end. I am going to get an extra set of irons to have in Florida.”
