Head Speed Pro 98" 16x19 = TSDV 118mm

I would say the control of each racquet directly correlates with the lower TSDV s.
You're dead right about control correlating to this value. It also has a huge impact on stinging choice.
I just went through four attempts at getting my Speed MP 18x20 strung right. At first I was approaching it as a "dense" 18x20 with respect to string choice. I then switched from 17g Team (used in my truly dense PSLGT) to 18g Touch (used in my more open PB10 Mid.). I was simply stuck in the 18=dense mindset.
WOW! Huge improvement! As one friend noted the Speed MP now plays like a much spinnier version of the Pb10 Mid after some tweaks to the weight and balance. Stringing it as an "open" pattern was the answer...it needed it's power dampened a bit with slightly thicker and stiffer mains. Stringing it as a dense pattern with a thinner main resulted in too much power.
Just as we all have preferred weights and balances we probably have preferred TSDVs. After lots of recent demoing And measuring I find too little control and too much power over 123mm or so.
