I was on the Standard Burner 9.5 with a stiff shaft which a bought new last year.
Yesterday after long consideration I went for a fitting with Taylormade on the R11 TP.
On the computer I was carrying 240 m with a ball speed of 140mph and launch angle of 19 and spin of 4000 rpm average (they had me hit loads of balls !) with the current club.
On the new R11 TP I started with 235m 140mph angle of 12 and 3000 rpm.
To cut a long story short I ended up after a few hours of messing around with an average of 295m carry ball speed of 153mph and launch angle of 12 and spin of 3200 rpm.
I think it depends on fitting. If I had of compared the two side by side with out hours of playing with the club I would of said it was not any better than my burner.
