I was in an AI smoke max td with a denali black 65s shaft. My driver swing speed is up about 12 mph since doing the stack (112 to 115 mph) so I got refitted and ended up in elyte td with the 65 tensi black xs, tried all of the big brands. I think I could have had similar results with a shaft upgrade in my ai smoke. I've played about 6 rounds since making the change and am definitely driving the ball noticeably better, but again think a lot is attributed to the shaft being easier for me to time up. I really do like the elyte at address, the glossy black top looks high end.
