They recommended that I purchase an adjustable Driver that will go as low as 8 degrees.
I'm 56 years old and have a Drive range between 175-220 yards using 8 degree Driver.

Go with what works if you are not going to change your swing. I am surprised that GT does not carry non adjustable drivers with just 9 degrees of loft. I've copied some info from a Ralph Maltby article which should shed some light:

The first reason is that manufacturers vary in the method and way they measure driver loft. The second reason is that some manufacturers simply put a loft number on the driver head because it is a very popular loft with driver buyers; but they want you in a different loft that they feel works better with their driver. The third reason is that manufacturing tolerances for loft, even from the very best head manufacturing companies overseas, will be plus or minus 1 degree from the specification. The fourth reason is the amount of vertical face roll that is specified. Since most modern 460cc drivers are actually hit above face center, a driver with more vertical face curvature will have a greater loft at impact than a driver with less vertical face curvature. I threw in vertical face roll since it is “real world” with modern drivers but it has no effect on the stated or measured loft which is always measured at ˝ the vertical face height.
The above reasons are why it is so important to get fit in a launch monitor or to actually see the ball flight on a driving range or the golf course.
