I just got back from there a couple of weeks ago and my stats are similar to yours. An IQ Tour Solid, pin down at 2000 grit surface, was money for me in team event. If I could only have gotten out of my way my scores would have been better.
For D/S I used a Menace at 500 grit, based on your list I would take the Sure Lock and add lots of surface to it. I had one good game in Singles (268), but quickly came back to earth with a 138 the next game. If I had been paying better attention, I would have jumped inside (same ball) instead of continuing to play off of the corner.
I took a Pitch Black for a spare ball and also because of a gut feeling about team event. Ultimately it was used for corner pin spares...I left more than I thought I would.
My suggestion what to take:
Sure Lock at 500 grit
IQ Tour Solid at 2000 grit
Pitch Black
