it was pretty accurate but i play titleist blades wich tend to be a bit shorter then a cavity back improvment club wich i could hit a 9i 150 i hit a 8i 150 with the blades somtimes a 7 depending on wind i thing 3 wood and driver were kinda short whick 3 wood usally goes 270-280 and driver tends to go 300+ down wind about 330 -350 in florida without much roll but pretty good calculations
