Free SPI ball, but which one?

I'm getting a free ball from any of Storm's brands. I'm just starting to feel competent with what I'm doing (just about a year in). I'm definitely speed dominate, working on getting my revs up. Currently I own:

• Storm Ion Max
• Storm Equinox
• Storm Tropical Surge
• Radical Outer Limits Solid
• Hammer Black Widow Mania
• Hammer Raw
• Motiv Venom Shock

The Ion Max, Equinox, Outer Limits, and Mania get the most use. Venom Shock the least.

My PSO/Coach suggested a 900 Global Origin, or really anything with a high hook potential. I was thinking about the Origin or Gremlin....or perhaps a strong symmetrical ball. Maybe Phaze AI....or lower diff ball to use after the lanes have transitioned, perhaps an IQ Tour. I primarily bowl at a high friction house.

I gravitate towards Storm. Silly as it may sound taking a sec to take a whiff of my ball up on the approach slows me down a bit.

Right now only bowling on a house shot (so yes, I know this is all overkill) but definitely want to start to tackle a sport/challenge patterns at some point.

Any suggestions? Probably not 1 right answer here but curios what you all think.
