How do I handle regional 'Akanie' while speaking Russian?

I’m planning a trip to Moscow and I’m worried that my textbook pronunciation of 'o's might be too stiff. I know about 'akanie'—the reduction of unstressed 'o' to an 'a' sound—but I find it really difficult to implement consistently without sounding artificial. Should I focus on mimicking a specific regional accent, or is it better to stick to the 'standard' pronunciation until I’m more confident?
