I would go with a ransom w/ a pin down layout to tame the back end reaction for medium oil. The burst has a low rg and it will read the lane early and it will be earlier on the back end than the ransom. You say you want something clean through the heads, if I were you I would go with the ransom. I think the ransom is more of a medium oil ball than a burst.
