Maybe this has been covered before but didn't find what I was looking for. Anyway, of those three I have only used the viper 100 gr and it hits where the field points do and groups really well. Just didn't know where the wicked trick or Exodus compares. I think the vipers will do fine with the elk but if one of the other two can hold up with the viper in accuracy and penetration but makes a bigger hole that would be great.
