Reference to 61.5 and 72 are about EASTERN ARC reception. If you are on 129 you are covered for same programming reception as is found on 61.5 and 72. In other words, it takes 2 sats in eastern arc to cover what the 129 sat does in the western arc. There are a few more programs on 110 sat to round out the full deal. The problem with 129 is line of sight (LOS). It is pretty low in the sky.
