You either want a ball for heavy oil, or one that goes long and snaps.  You can't have it both ways.  Where is the CG located?

If you want length, pin 4.5-5.5" from your PAP is good.  Typically the pin is over the fingers somewhere, but again it depends on your PAP.  You then tailor the hook shape by where you place the CG.

If you want the ball for heavy oil, usually the pin is placed 3-4" from your PAP.  Usually the pin ends up near (outside) and below your ring finger.  Again the CG is placed to fine tune the hook shape.

The more info you give us, the more we can help.  Revs, style, axis and tilt,  Positive Axis Point, average, lane type and conditions, line you are trying to play....

I'm not up on Hammer's line, but the Blade Particle should be fine except for flooded conditions.  The Diesel Particle will handle a bit more oil than the Blade Particle.  It won't necessarily hook a bunch more, but it might fight through oil that the Blade will not.

If the Blade is the only ball you have, I wouldn't alter the cover since you see many different lane conditions.  If you want the Blade to handle more oil (at the expense of being versatile), sand the cover to 600 or even 400.  Ebonite/Hammer recommends Abralon pads on their equipment.  Scotch-Brite should be a safe equivalent, but sand paper is generally not recommended for particles.

Remember, particles don't always out hook reactives, they just will give you some hook when reactives will not.  Reactives skid on oil and hook a bunch on dry.  Particles spread the hook evenly throughout the entire lane.
