A bigger rear sprocket will increase torque more than changing the rollers, but it will also have a bigger effect on top speed. For serious hills though, I think a gear change is the only option.
Contrary to what most people experience, I didn't lose any top speed when I changed to lighter rollers. The only reason I can think of is I took a lot of weight off my buggy? IIRC I used 11 or 12 gram rollers.
The light weight of the buggy also helped a lot with acceleration and hills. Keeping the valves adjusted made a pretty decent power difference too.
