I am going to add another coil to my line-up soon. I have the 9X8 and a Shadow Super 7 so far. I mostly hunt trashy campgrounds and some sports fields. I'm leaning toward the 5.75 concentric for those trashy campsites. Is the 5.75" noticably better in trash than the 7"? If there's not much difference between the 7" and the 5.75" then I'm thinking about the 8.5" widescan for the sports fields. Thanks!
