I would recommend going to see a certified Titleist fitter. Getting the right shaft and head makes all the difference. Getting a shorter shaft could help your issue but that is something you need to discuss with a qualified fitter. My shafts a 1/2 over and my heads a 2* flat. Am 6'2". Theri are a lot of variables that he will check. Not all to do with height. Arms length is a factor. The new Titleist irons; T100, T150, T200, T350 are all forged. You might check into getting the older model T series, if you want cast irons.

Forgot to mention that one of my buddies that plays in our men's senior league is on the short side and is much older that you. Plays nothing but Titleist equipment. He also is five feet tall, in his 70's and always get fitted for the correct clubs with our Titleist certified fitter with great results. Hits his driver long and his irons straight with a great deal of accuracy. Has no issues with getting a set.

Well, you now qualify for a professional fitting on two accounts. Your height and now age are outside the norm for stock models.

In Michigan it is a little late to get an outdoor fitting with a Titleist fitter. The fitters sponsored by Titleist can work with you on lie. The range is -2 degrees to +4 degrees upright. So a -5 degree is a stretch. Titleist has increased its efforts to meet the needs of women golfers. Which is not offering matched pastel sets but offering options for the same products but for more specialized setups.

From the web page there is a fitting tab and you can contact Titleist for a virtual fitting. The consultants are actual fitters employed by Titleist. That person can help direct you for solutions to your lie request. Not that you would actually order clubs based on a virtual fitting. In my case, they helped me get additional LH heads for the TSR-1 line to my local Premier fitter. Every top fitting site has a full line of RH tools. Not so for LH golfers “of a certain age“.

As a long time Titleist user I would encourage going with Titleist however, if they can't fit you for your required lie I would suggest looking at Wishon Golf. They have iron called 771CSI which is a 431 stainless steel iron bendable up to 4 degrees flat- depending upon the proper lie for you this may suffice as there are no consistant standard lie between manufacturers. Good luck in your search.
