I found that a long double offset has a lot of mass, and needs more pressure than you'd think. There were places where I had to use it, but I tried to find other ways whenever I could. I don't remember specifically how much pressure I had to use, but the exact number would vary depending on the gun and other factors anyway. Don't be afraid to crank it up to get the result you need.
