I have the benefit and pleasure of being on staff with Roto Grip and drill for some local staffers for other companies. One of them being Track. His Kinetic we drilled pin to pap 3 3/8 and mb @45 degrees. Wanted med length and have a pretty good reaction off the dry. This was the trick for him, but tends to be a little touchy on THS.
My Illusion I have drilled 45 degrees, 5 inches, 35 degree (Dual Layout System).
Basically I wanted to have a late mid-lane move, with an aggressive back in motion. Again, for me it is way to much for our THS, but I am able to go to it later in the league night. My best look with it has been on Shark pattern.
Hopefully this helps.
