I have 5 deer to my credit using Rage, including 3 bucks. I use the 2 blade head and draw weight around 65lbs. My first was a severe quartering away angle, I hit him way more back and the arrow went all the way in, was not a pass thru, deer made it 100yds, bad shot. The next was a 4pt at 22 yds, great shot, no pass thru but AMAZING blood trail out of both holes, deer was down in 60 yds. The next 3 were between 8-17 yards, all were complete pass thrus and each deer dropped within 50 yards. I guess it all depends on placement but my experience shows complete pass thru more than half the time. When I was a kid, I was shooting a 50lb bow with fixed Satellite heads if you remember those. I got 2 deer, both does but both pass thrus. I think with todays muzzys and thunderheads, she'd have no problem with penetration at lower draw weights
