I used them and the originals. They are ok but I didn't see any difference in them and others. I may have some left. I'll check and let you know.

 

Thank you for the feedback on these!

 

I’ve never shot them, but like the idea that the base of the vane curves around the arrows vs spin wings are flat. So to get spin wings to look evenly distributed on the arrow, you really need the tape the stick and they need to be applied pretty consistently in the same place each time, which takes a lot of time.

 

Not good. They fit nicely onto the shaft but that's about it. They don't seem to spin as much as other vanes. They easily take bends.

 

Well, spinning (fast) isn’t necessarily a required or critical function. Drag is.

 

Seen this ?

 

They didn’t seem to group either

 

Old original version was too stiff, most recent versions have reasonable flexibility, so are much better in the wind.
My son ran extensive comparison tests from August last year, outdoor and indoor, and ended up switching to the new Jet 6 1.75 for outdoor and 2.00 for Indoor on his X10 and CA320 arrows.
And, yes, for sure they are easier to assemble on slim shafts ...

 

Tried them, only difference I seen was they cost more!
