Plus, they say the fly just like a field tip at high speed. These don't say that...

SA, here's what Rocket says-



Penetration — Rocket Aeroheads will out-penetrate conventional vented broadheads of considerably smaller size. In fact, our new Stealth series Aeroheads penetrate up to twice as far on foam and plywood combinations as conventional vented heads of similar cutting dimension. On game, Rocket Arrowheads snake uncannily along the path of least resistance. The patented offset blades cause Rocket Aeroheads to twistingly penetrate game to deliver a devastating spiral wound channel. They will readily shatter the largest bone, but not if there is an easier way around. They tend to twist and glance off of bone, conserving energy to cut more vital tissue.

Rocket Aeroheads do not take the path of least resistance when it comes to impact at an acute angle. Because the blades form an angle with the ferrule, when a single blade catches, it leverages the chisel point into the target. The blade tips are pointed rather than rounded to pull them into the target with an angled hit. This feature has often turned an otherwise glancing missed shot into a successful hunt. Typically, a slash wound leads up to the point of entry. Tight angle shots should be avoided, however, with the longer-bladed Aeroheads as the arrow may turn on impact reducing penetration.

Maximum Damage — The small on-center blades of conventional broadheads often leave a small surgical cut, which can easily close up. The spiral wound channel left by Rocket Aeroheads is anything but surgical. The offset blades of Rocket Aeroheads are set back from the chisel tip. As a result bone is shattered and flesh is stretched before the blades strike. Blood vessels, arteries, and flesh under tension spring apart when cut for maximum hemorrhaging. Together with the extra wide cutting diameters of Rocket Aeroheads you'll have a trail, which leads to recovered game.
