Or you could just screw on some Thunderheads.Thunderheadsare the bomb-diggity!"

If you want all sorts of pertinent data you're still only getting input from what people prefer. In real world test I've shot probably 50 deer with Thunderheads. Virtually all have been passthroughs at distances to 40 yards. The couple exceptions were larger deer and I whacked a shoulder going inor stuck the off side shoulder. They're sturdy(I've only EVER had one blade chip and that one took out the spine. They fly with my field points once the bow is tuned. When you get an arrow set up the Thunderheads are interchangeable, although I set up each arrow with it's own broadhead and never are the two parted. It's just that I always usually bust an arrow after one or two deer, certainly by the third. The old reliables have been around for years for a reason, they work, they don't bankrupt you like some of the "NEW" German made things do, and they've been killing deer since before most were around. I've killed a tad over 80 deer with a bow. I've used probably 8 or 10 different broadheads in 35 years of bowhunting. I see no reason to change to anything new and improved when Thunderheads are the diggity.[8D]
P.S. I never tested them on rocks, plywood, old cars or barrells.... just deer and my advice is Free. You don't have to subscribe to anything other than the theory... "If it ain't broke, don't fix it".[8D]
