I've got both...
Haven't drilled the Toxic yet, but after I get it drilled, I am going to take it down to 2000 grit with polish to help fight the carry down issues the ball has in OOB condition....
Drilling it for skid/flip to help with medium/light lanes, will give me a different line than my BV, which is set for a strong arcing move to the pocket...
I have better luck with the BV on medium to a light heavy oil pattern than the drier patterns
