Talked to a person that had just tried slick tricks for the first time and he indicated that they flew as advertised, but that he got a whistling sound off them when they cut through the air. Anyone else had this experience?

Yes, I shot them had the same happen. Lots of air noise, i mean lots

I used them last year and will be using them this year... I shot 3 animals with them and they never heared them comming.. 1 was at 33 yards, 1 at 27 ans the third wat 17... I shot them a lot and never noticed and noise from them..

I've never heard the whistle, but only shoot at 270fps.

Is this a high speed issue or a possible tune issue?

(arrow possibly leaving the bow with head not square enough to target so the wind catches the blades from the side as the fletching corrects the arrow?)
Just a guess...

I shoot the last week at my friends house and didn't hear a sound!!!

I have used Slick Tricks succesfully....one shot, one deer so far. I didn't hear any noise from the broadhead, I did hear too much noise from the bow. So I upgraded to a Mathews Switchback XT.... but will stick with the Slick Tricks.
