Feather performance

[Biggamefish]

 How much of a performance change do you think someone would see switching from a 5 in parabolic feather to a 5 in shield?

[kopfjaeger]

I shoot both and I haven't noticed any change between a 5" parabolic and a 5" shield. Some say there is a noise difference.

I think the amount of surface area(size) would have more affect that the cut pattern.

[GCook]

I shoot 4" in both cuts and cannot tell any difference.
