Well Awshucks, I have been using a single cross hair for a long time [about 20 years] and I put the vari-zone on and it work fine but I am not sure what I will end up using for hunting, I have taken an average of 2.5 deer a year and a bunch of other game and never missed or lost any so I study all changes very carefully before using them hunting.
As for the post I was just interested in the way other people look at and deal with trajectory. Lee
