Just trying to bump this up to the top. Really interested how people playing the TSi3 are utilizing the sliding back weight. Face impact location or promoting draw/fade?

I'm no expert Jason, but I can't imagine where you ultimately decide to put the back weight is going to have much if any effect on mass behind the ball.I think if it were me, I'd pay wore attention to ball flight, and set up the sure fit hosel and back weight in tandem, to give yourself optimal ball flight and launch.

That makes sense. In theory, more weight centered behind the ball has to give it more ball speed but maybe not significant to the point where you'd lose meaningful yardage if it doesn't match your impact spot. This is where a guy needs to invest the 20k into Trackman....:) Would ultimately rather hit the fairway than gain the extra few yards from having the weight right in the center.

I play my driver on the B1 setting, just to help me keep the ball from going left. Some days I feel stronger and club feels a little lite, I will move the weight to the T1 position to help slow the clubface rotation down??? I look at it as what ever works to keep my drive in the fairway. I don't think there is any right or wrong set-up, it's just what ever works best for individual player. That's why I love the surefit system with 16 different adjustments along with 5 different weight settings, somethings got to work! LOL
