Yes, that's the one. My grip spec. is 5.5 over and 15/16 up. Most of the balls I have similar specs to what you said and a good share of them have balance holes added.
I've played with Storm's VLS spreadsheet a bit. Have taken the results I got to the PSO and he's agreed that the choice is pretty good.
From the flare article by Blueprint one can conclude that the drilling angle doesn't affect symmetrical balls much at all, but the pin to PAP distance appears to have a greater effect.
The drilling angle seems to affect asym. balls more than symmetrical balls. The VAL angle affects both.
As one changes the VAL angle you can see that the pin buffer distance changes.
I'm going for a lesson either later this week or early next. I think that I'm likely speed dominant, but my speed has come down and my revs have increased a bit. I might be close to balanced, but I think I'd like to get the totals of drilling and VAL angles down a little from what some of my balls have today.
Thanks for your comments. Oh and BTW I'm on a THS. Just trying to learn and understand things better...
