The closest thing I got to Tour Bite 17 is Dunlop Black Widow 17. A bit less power, but pretty close in terms of spin and general feel.
Black Widow is I believe the 3rd softest poly on sale today behind Pro Hurricane 18 and Head Sonic Pro 17. When marketing it, Dunlop even said its softness negates the need for hybrids to make the stringbed more comfortable. Tour Bite, however, is pretty much always considered a stiff poly.
