I've seen a few different threads about the C16 and the resulting 917 design from that concept but I didn't see any info from a titleist Rep as to any actual advantages of the C16 over the mass produced 917. I love my 917, first driver I've hit well in a while, was just thinking if the C16 is basically the same but offered a little extra advantage I may give it a try, there are a few floating around on eBay in the $500 range which is what I paid for my 917 so it seems pretty equal now as far as a money outlay, any thoughts? Any titleist Reps on the board that could point out any advantages to the C16 and its more unique materials etc etc?
