I would use the 100gr. The only issue i had with the tricks was because the heads are steel and after you shoot thru you deer and hit a rock unlike conventional heads they don't break apart to save your arrow, These heads have no give you arrow is shot. Small price to pay to have a blood trail like somebody poured it out of a 1 gallon water picture. Like the rest of you guys I was weiry of these. Hell I switched from muzzy's, nobody switches from muzzy's. Try them folks, small head big hole. short tracks.
