No one can give you an honest answer for that. Some guys like the single pins and some the multis. I prefer the multi pins because at the moment of truth I don't want to be messing with adjusting my pin setting. The single pin users claim that it obscures less of the target. I can see that even though I've never used one.
When on stand I range different objects so when my target approaches I know what pin to use when it presents a shot. Still hunting, if I have come within range, or one comes to me, I only have to hit him with the range finder.
Another thing I like about the multi is if I have a deer at 40 yards and a branch at 20 I can put my 40 yard pin on the deer and check the 20 yard pin on the branch. If it is above or below the branch I have a clear shot. Something you don't have with a single pin.
Now a single pin user can set his pin at 30 yards and hold low for 20 and high for 40.
