You need some Axis Tilt

Colton, 

You will certainly want to get that launch angle down.  I'm not sure what loft your driver is or what shaft you are using, but ideally you want to try to get down to 13-15* launch, without sacrificing spin (being too high) in any way.

I'm currently using the TM R9 and has a regular flex. I'm going to buy a new driver with a stiff shaft. But do you have any tips on how to reduce my launch angle? and why it is so high?

dont waste your time and money on a driver w/o getting fit.

if your speed is in the 110-115 range a stiff shaft may not be right for you, and all shafts/flex are not created equal.

With 110-115 mph swing speed, you should be close to X flex.  With that swing speed you should be hitting near 300 yards.

If you are using regular flex, you're probably hitting drives with the trajectory of a 7 iron or you may have it so far forward in your stance that you are losing power.

My swing speed is 90 miles per hour tops and about 82-85 average and I hit it over 250 yards occasionally and I'm using a TM HT Draw with M flex.  My normal drive is 220-240.

Difficult to help without knowing the spec on your shaft. Sounds like you have a soft tip/high torque.
