The I10 and G10 are about 10 years old. From the Twin Cities, I'd wait another 75 days or so until I could get an outdoor fitting. If you got the clubs new, then you definitely want to get fit to decide what equipment will work with you today and for the next 5-8 years. There are so many variables with which club and which shaft match you the best, that you really need a pro to fit you. Besides the 7 iron and 4 driver choices, the permutations with shafts is beyond my ability to estimate the possibilities off the top of my head. LIfe was so much simpler 40 years ago. Also note if you can hold off until later in April or into May, appointments at Titleist Thursdays in your area are free with some of the widest choices to be fit with qualified Titleist fitters.
