Went today got tested on launch monitor with my taylormade r7 425 with re ax 65 stiff shaft 8.5 loft with mid tip my clubhead speed averaged 107. Ball speed was 150. Launch angle was 14-16. Killer was my backspin which was 3800-5000 rpm. The guy doing the test thought I may be hitting down on the ball a bit that measurement was 55 (cant remember exactly what it was called). He said I needed to catch it more on an upswing. He said maybe go to x-stiff shaft and get the tip stronger which I tried a few swing with the burner see details below. Any suggestions please I want to max out and get the right equipment or swing. do I need lessons or new equipment. My best drive out of appx 20 drives flew 262 rolled out to 282. I even tried to new burner 9.5 degree loft with 75 gram shaft with stiff shaft and stiff tip didnt help much if any. PLEASE HELP.
