Relaxation Parameter Recommendation?

I am using a periodic boundary condition for the first time in Fluent. The grid is a simple round tube and the Reynolds number will vary between 30 and 2000 (always laminar.) I have no experience picking good under-relaxation factors, and I'm currently ending up either with something that doesn't converge or extremely slow convergence. Can anyone provide me with a good starting point for the underrelaxation parameters or tips on how to refine the underrelaxation parameters once I have an approximate solution?
Thanks a lot!
