I use GS x 6
At 250 kts, to descend 10000 ft requires a descent rate of about 1400ft/min over 30 nm. So using GS x 6 gives me a descent rate of 1500ft/min. I find it gives me a bit of altitude to play with when I have to be below a certain altitude by any given waypoint. Then again, I handfly a B1900, cant keep it quite as accurite as an autopilot when Im bouncing through the soup
