Since you seem to prefer Storm, you might consider the Trauma Response if you can still find one.  It makes a pretty good heavy oil ball, but it does need oil to work well.  Since they are already out of production, you can probably find one at a pretty decent price.

For heavy floods:

Super Carbide Bomb, Pro Zone Azure, Chaos, Angle of Evolution Tour. I wouldn't recommend unless you see goo-gobs of oil because these balls will probably look weak on med-heavy conditions as they would burn up most of their energy.

I alos disagree about the Duece and the Eliminator being a good heavy oil ball for the normal bowler.  but if you have revs like Pchee2, about 600 and speed like SrKegler, about 13, you could use the Duece or the Eliminator.  So I won't say they can't be use on heavy oil.  But for the mer mortals,the bowling balls I prefer is:

Evolution Tour
Lane 1 Super Carbide Bomb
for Storm the Response
I'd like to say the Super Freak, it has the coverstock but I only have three games on the ball.
The Freak and the Mutant can handle a lot of oil if you keep the coverstock dull.

But I'd like to add again, if someone with a ton of revs threw some of these high loaded particle balls, they might still get the ball to roll/burn out IMHO.

for a heavy oil ball look no farther than brunswicks swamp monster. this ball has a VERY aggressive particle coverstock. drill it up for maximum hook and you'll think your name is robert smith the way the ball will hook.

steven, as usual i find it amusing that i'm the only person you ever seem to make comments about.....nevertheless, the first time I, MYSELF, threw a brunswick swamp monster i literally was hooking the ball like mr. smith. i could seemingly miss any amount right and the ball came back with no quit. i have never really been comfortable with a deep inside line but this ball made ME( and probably others )feel like they could now play this shot if they had to.

you are right in one respect, though. no ball can really hook on a flood. you are looking for mid-lane roll. this lane condition would favor my game. since i rarely throw the ball 20mph anymore slightly slower speed and an aggressive particle ball would work well on a lot of oil. it would help to use a release that favored roll as opposed to spin.
