For a THS on Synthetics, I generally try and use some surface b/c the lane surface is so hard (Brunswick Pro Anvilane, I belive)... Plus this THS plays a little thicker than normal. I go to my Black Widow Sting.
For a pure THS, a medium one, I'm throwing my new Visionary New Breed Pearl. Pretty strong off the spot (not flippy), drilled to be a continuous arc, it DOES do that.....
For extreme dry THS and "those night" where it gets fried...., pull out the 5 1/2" pin Cherry Vibe with Valentino UFO....
Again, this works for me. Good luck in your future purchase..
