i shoot thunderhead 100 gr. heads. they fly great and do a really good job during and after impact. Everyone has their own prefences most as good as others id just pick a head that flys well for you and is sturdy and stick with that head. and dont use expandable heads. fixed blade heads will serve do you a lot more good in the long run because on shots that arent pass thoughs expandable blades fold back up and dont continue to cut inside the animal like fixed blades do and that can make a huge differnce. good luck out there.
