Over at MLBTR, they have done some slick engineering to determine the Type A/Type B status of various players to determine compensation for signing arbitration-eligible. Click the link for the full list, but here's what we're looking at, Astros-wise (reminder: If the Astros offer Pence arbitration, and he declines, and the Braves sign him in the off-season, the Astros get the Braves' pick. If the same scenario happens with, say, Brett Myers, the Astros get a sandwich pick between the 1st and 2nd round).
Hunter Pence: Type A
Wilton Lopez: Type A
Michael Bourn: Type B
Brett Myers: Type B
Wandy Rodriguez: Type B
