"The RSI testing data has very changed on this this string from:
2012 to the latest report (2014)
In 2012:
Big Hitter Silver 17G:
Gauge: 1.26 mm
Stiffness: 231
Tension Loss: 18.15
In 2014:
Gauge: 1.20 mm
Stiffness: 173
Tension Loss: 23.74"
The 17G of the Silver is a new string (1.20 mm). Tourna is selling the old 17G as the 16G now.. so one needs to be careful about what string we are talking about.
The new 17G is much more powerful, softer and spin friendly than the older Big Hitter Silver 17G. If your memory is tied to the older version you are correct.
Here is how it is now:
Big Hitter Silver 17G (1.20 mm) - New Offering (about 18 months ago?)
Big Hitter Silver 16G (1.25 mm) - Old 17G Silver string (More like a 16L)
Big Hitter Silver 16G (1.30 mm) - Gone
Having played all of versions and the ALU Power.... The new 16G (old 17G) plays the closest the ALU Power IMHO.
Most of the user feedback for the 17G listed with the string is now no longer valid.

. The older feedback would of course apply to the current 16G version.
Topspin also changed the Cyber Flash 17G as while back.. so maybe there is a connection.
