I have the 06 ones and they fit tight. I didnt have a broadhead wrench for 4 blade so i kind of used some needle nose pliers to grasp and twist tight! Hope thats ok.

I have the 06 just got them this week they fit perfect with no movement of the blades.

I'm wondering if I got my 05 blades and my 06 blades mixed up. I've got some more confirmed 06 blades at home that I'll try out. I bet they aren't loose.....

qzg38, if you look at the cutting edge of the blades the German blades look much different than the older blades. There is a wider "ground egde" on the new vs. the old.

While we're at it the German heads are a tad on the rough side on the very back side of the blade (the flat non-cutting portion).
