Whats tightly correlated to Oil?

EFTs like USO are not, they move down with oil but not up with oil and as a result are not too correlated. Are there any alternatives, any suggestions (apart from trading oil futures)?

 

DXO is pretty good, though it's a 2X.

 

Stay away from the USO and DXO because of the front-month roll.

Your purest correlation will be with the OIH, which is the Oil Drillers Index, comprised of RIG (17%), SLB (12%), and DO (9%).
