Some thoughts:
Long pin-CG balls, likes yours, tend to take longer to stabilize, that is, to get into a roll, compared to the same ball with a more "normal" pin, like 2.5 - 4". This sort of counteracts the lower RG concept. I'm kind of susrprised your driller put the pin so close to your track and so far over, unless you had fairly slow ball speed. At the 6" pin to PAP, it will be good for more broken down or blended conditions, rather than fresh or wet/dry conditions. Your long PAP usually but not always implies a fairly early rolling release, but he, your driller, should know your game better than strangers here.
If it is going too long before making its move, and if it still has its polished cover, you can haze the coverstock lightly with a green or a grey nylon pad to remove some of the shine. Do that lightly and test it on as normal a house or league shot as you can. If it's still too long, haze (roughen up) more of the shined area.
