I have recently experimented with using differing amounts of backspin as I got bored always moving the dot all the way down, and I found that 3/4 BS was far more effective , both in distance and trajectory. This was in low wind situations, like 8 to 15 mph stuff.
On courses like Kiawah, Okie and Congo I am getting 300 plus yards regardless of whether it is a t/wind or h/wind in low wind.
A hypothetical bet to anyone - if I was to play Olympic and hit every fairway, but was 30 yards behind you in distance, I think I would take the $$$$
