Maybe now most here are already using the Pria Complete, but since there are three kinds-everyone needs to be specific. The thread only said "Pria" and the originals are what it looked like you were all discussing.
Newbies can come here and read-and think that the 110 calorie original Pria bars are an okay substitute. When discussing subs for the plan, specifics should be used-because when you go into the store-there are regular Prias, Low carb Prias, and Pria Completes-very easy for someone to grab and sub the wrong item.
There are Kashi Go Lean bars, and there are also Kashi Go Lean Crunch! bars-with different nutrition and calories...Powerbars have a few different formulas as well, as do many brands. Just be specific when you talk substitutes, if the brand has different forumulations. This information will really help new people coming to this forum.
