Truglo Strut Stopper Xtreme or Truglo Gobble-Stopper XTREME ?

[ranger400ex1994]

Which one of these would work better in my 870 super mag with the 26" barrel? I have never shot heavy shot but i might give it a try this year. I have always shot remington Nitros 12ga 3 1/2" 2oz 4 shot with pretty good results in my factory rem super full choke.
