What do you think of these heads? Looks like they would be easy to replace blades on and might help with speeds over 280??

Here's a pic!

Here's the left spin

Reminds me of the old Koplin broad heads.I killed 2 deer with those things

I saw them too over on the website. They should fly very well and be supa-sharp knowing Rocky Mountain (i've used the Ironheads and Titaniums). Personally, If ended up going with one of the new "mini" fixed blade heads I think I'd go with the Wasp Boss SST (100 grains, 3 .027 blades, 1 & 1/8" cut). I've had excellent luck with the regular SSTs(75 and 100 grain);it's my fave fixed blade head.

Interesting idea but I question the practicality. I am sure the blade angle helps promote spin and thus stability and the potential for increased penetration but I wonder how much it will actually contribute for folks that already have a hard helical setup on their arrows.

Do they at all tout the blade angles ability to bore out a hole versus just cutting through?

I'm curious, as they look just like a Rocket mechanical with the blades deployed, and Rocket says that's why they use those particular angles.

I would think it would hender penetration but what do I know[8D]

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.
