What I would love to see is for him to add one of the old TM Burner drivers made from 2004-2006 into the mix. My guess is it would be just as good as the R11.
Last year at our yearly fundraising golf tournament, the guy who won longest drive was actually hitting a TM 320 Ti, released by TM in the year 2000. There were actually two guys at the tournament hitting that driver, and both of them were among the best in terms of distance. And those old drivers were obviously way easier to control than the SLDR.
