Sixpack,
I think you're a long way from needing a particle ball if your Hot Wire is just barely not enough for this oil pattern.
There are a bunch of stronger resin solids that should do more than enough for you without going to a Triple XTreme, which, in my best guess is 2 - 3 steps stronger than the Hot Wire.
In Storm, there's the Super Charge and the Hot Rod Pro Stock (which is about 1/2 step stronger than the HW due to its core).
In other brands, there's the Nemesis, Retro Resurrection (Rot-Grip), Shock, SHowtime Sanded, Freak-a-Zoid, among others.
In the Miscellaneous forum, there's a current thread entitled, "Looking for well recommended SOLID Reactiv balls". Several of us have made recommendations ranging from medium-heavy/heavy oilers to medium/medium-heavy solids. Take a look in there for a possible solution.
FYI, from my eye, a 75 degree is also called stacked because pin& CG are often one on top of the other. 75 degree drillings are typically your flippiest drill, according to most professionals AND depending on the ball. 10:30 drillings are usually on the order of 45-60 degrees and are arc drillings unless you are using a skid/flip ball like many resin pearls.
