This all sounds too much like Albuquerque and Syracuse in 1999 and 2000. I haven't gone yet, but you guys make me think I'll be using my Bolt Pro again between 20 and 24 with breakpoint around 12/13.
Bolt Pro is very mild solid, kind of in the ball park with an old Beast solid. I have sanded it to 1500-2000 and leave it dull, using Doc's Elixir these days. This surface gets good length almost anywhere. Pin is over the ring finger for extra length; CG is below, since this is not a flippy ball. It has a mild back end.
I'd suggest something like this. The vast majority of mild balls today are not truly very mild. I think the AMF Courage (a solid) or the WIld, if you sand them very fine like I did, would make good balls for this shot.
The idea is not to get so deep, like inside the 5th arrow. If you do need some flip to the ball and drilling to recover enough. Around the 4th arrow I still had enough so I didn't need a lot of revs to make it hit.
Targeting:
If the oil line is around 10, target 12 to give yourself some area right and some pull, if the ball and your delivery will allow. This pseudo-sport shot requires the minimum backend of your ball and your delivery to maintain some sense of freedom of swing. If you think you must hit that 1 board to score, you're not likely to hit it very often.
