My first Titleist club was a pair of Vokey wedges back in 2003.  I then got the 983K and was hooked.  

I still remember that I had some Titleist irons about 10 years ago, but cannot remember which type it was

Got my first set of Vokey wedges this past year. Sm5s are the best wedges I've ever played. After I realized these clubs were the best in the game, I upgraded to all Titleist clubs. Now I have a 913d3, 915f, 915h, 716 ap2s, and Vokey wedges. A lot can happen in one year, now I just need a Scotty Cameron

A 56/14 Vokey was my first in about 2000.  I carried that thing until about 2 years ago when I replaced it with an SM4 of the same loft and bounce.

I won a set of DCIs in a golf tournament years ago.  Was not fitted for them and never could play well with them.  Too short and went to another brand after about a year of playing with them.  Floated around with other clubs then was properly fitted by a Wilson Staff rep and played those for about a year and the rest is history.  My next step after that was seeing a Titleist fitter and am now 100% Titleist.   

My very first set of irons were Titleist Acushnet AC 108. This model came out in 1972 (I think) but I bought these used in the late 70's. I've had Titleist clubs since and don't plan to change.

My first was also an Acushnet Bullseye putter in about 1962. Then I got an offset Bullseye shortly after that. The grip was flat under the thumbs, leather wrapped with wood handle instead of steel until it met with the rest of the putter shaft. The heads were brass and had a buttery soft feel to them. A truly great putter!

Yeh me too great for short putts but the Cameron's are better for me on the longer putts.

First Titleist clubs were my DCI's .  Loved them.  

Mine was a set of DCI762's 3-pw with dynamic gold S300 shafts.  Had them about 5 years.

First Titleists were DCI irons with the loft angles stamped into the soles - very cool.

I think my first Titleist was one of the original Advanced Performance wedges (hope I remember the name correctly) back around 1992.  I remember holing out with it the first round I played with it in the bag.  Unfortunately, it was after hitting a shot into a hazard and dropping - but it was a memorable par!

First iron set was a custom grind set of 842 forged blades in the mid 1990's.  I still have them, but I was never happy with the shafts and tried a few different shafts without success.

My first was Titlelist 914 AP1 irons

1996 or 97.  962 black unstamped. Still have them!  Quality LH clubs were kinda hard to find. Still play them every so often..

My first Titleist was DX tourney irons and Mcgreger tourney woods, 1965

Gold Triangle DCI's for me back in1992.  My fiancé bought them for me for Christmas.  Have been married to my wife and Titleist ever since!  Currently play 714 MB's, 915D2, 910 (3, 5, Hybrid), Vokey Wedges, Scotty Cameron Putter and ProV1x.

SM5 56 degree wedge - slowly building out a titleist bag after that purchase.

My DCI 962's. Great set of irons. 

A set of Titleist Tour Blades from the 80's. Added the 1 and 2 and still play them today. Hit the sweet spot and NOTHING feels better. 

My first were a set of Acu Flo irons and woods in the early 80"s. They were terrific.

Every club every year! Its a sickness...

8* 975d driver given to me by my dad. It was my first club with a tour stiff shaft. Gamed it until I bought my current 910 driver.  Still have it for grins

Back in grade 7, I got a vokey 52 degree gap, 2009 SM

titleist Pro100 irons 1-pw and i still have them

The first set of irons I bought for myself was a set of Titleist DTR's. I have not hit another brand since.  That was probably 1989. I have slowly switched my entire bag to Titleist. Great products. 

My first Titleist club was a set of irons that were way ahead of their time. Can't remember the model but they had a pair of tungsten weights on the back. Had them in the 70's I believe. Anyone remember the model name?  

pro 100

Mine too, Titleist 975, but the 3 wood.  A strong 3 wood, it was either 12.5 or 13 degrees, bore through shaft and the best 3 wood I've ever had.  My home course at only 6500 yd long par 71, I used that club to tee off on 10 of the 11 par 4s.  I loved that club and would have slept with it.  BUT, someone else must have, because it was stolen out of my bag at the club.  The club was or course mortified and said they would replace it, but that was 2 years later, and they bought me a new one, different design.  No more bore through shaft, and it never felt the same.
