Hey Rage guys, check this out.
 

This is not a war thread about broad heads.
I have used Rage two blades for 4 years now with no issues and have killed nine archery deer with them.
I still use my compound bow, but last season I bought a 2009 Parker Cyclone crossbow.
I did kill a deer with it last year and I was using a Rage two blade broad head.
With the speed that the Cyclone is hitting ( 350 fps ) I worried about the blades opening in flight.
What I did is take a thin slice of 1/2" heat shrink tubing and put it on the closed blunt end of the blades.
This gave it a little extra tension in the closed position, but still easily opens on impact.
I have shot the broad head this way and it is flying just like my field points, but is opening on impact upon hitting my target bag.
So between the Rages O--ring and the heat shrink tubing I don't think there is anyway they are going to open in flight, yet it is small and soft enough to pop right off at the target.
Just thought I would share it with you guys.
Here are some pictures.

neat idea...im shooting compound..soo hopefully my rage broadheads will continue to do the job

i like your thinking sir.

That's a good idea. I think I'll also do that to mine.

thats pretty cool!

The little rubber bands from Wal Mart work good too!
