Remember, on truly heavy oil, it's not so much about the amount of hook as it is about the amount of roll you can generate to get entry angle to the pocket and continuation through the pins.  (Again, we're talking about truly heavy oil, which you aren't likely to see outside of certain tournaments, and also doesn't just mean long oil, but a high volume of oil!)  The Special Agent has a low RG core and the solid R2S coverstock that just loves oil anyway.  Depending on your release and ball speed, plus the nature of the lanes you're bowling on, it should be a good matchup for heavy oil, especially if you keep it sanded to a lower grit.

If you are facing a medium/heavy condition and you need to generate more angle on the backend to get better carry, something like the Attitude Shift may work better for that.

I concur with the above statements. When I was bowling in the PBA Experience and facing more oil than I have almost ever (there was on tourney I bowled in that was 50 feet double coated gutter to gutter...what a disaster that was). But every week before the heavy oil patterns (Shark and Scorpion in my experiences), I would sand my Passion to a fresh 500 Abralon, and after my set clean the crap out of it. Next week, hit it with abralon before bowling, clean the heck out of it after my set. Ball maintenance is key for a consistent reaction, and heavy oil gets annoying to deal with if you don't keep up. Hope any of this helps, and good luck in your tourney!
