I have used the game tracker silvetip mechs. the past two years. All my shots were broadside double lung and they have gone through whitetail like melted butter(7 deer, 4 pigs). Some people say these are "cheap" and they are but where I live there is nothing but rock so if you miss you can kiss your broadhead goodbye. They do make an awesome exit wound. For large game I use Muzzy 3 blade.
