TPS Pro Stock Blades

[estovlo2 0]

I have one of those TPS pro stock blades (actually retail) and the logo is red on it. Above the logo, it says 40% stiffer. I looked on a few sites for these blades as I'm looking for new ones and they all have yellow logos without the "40% stiffer" writing above it. Are the yellow ones the 2005 model? Are they still 40% stiffer?

It's the same blade.
