I've been playing for about 5 years now & I've had multiple lessons. To this day I'm subject to go out and shoot between even and +5... I'm also subject to shoot 90-100. My putting is always above average chipping & pitching fairly consistent, and my mid to short irons aren't bad... Driver, woods, & long irons are either ON or OFF! My backswing is too fast & b/c of this my elbow and wrist collapse @ the top (to the point where I'm worse than John daly) all this causes inconsistent misses, sometimes right, some left, and some straight. The 90+ scores come from penalty shots off the tee shot & the 70-80 scores come maybe 1-2 times out of 10 when my timing is on. I'd like to have some tips or drills to slow backswing down & stop at parallel.
