I have both Slick Trick magsand Spitfires in my quiver.
I've never killed a deer with either head (I did use the ST standard once last year).
Hunting from a blind (no mesh) with a maximum shot of 30 yards or less.
Both heads fly great.
Bow / arrow combo generates 69# of KE
I've been alternating which head goes up to bat each time I hunt, but no deer have cooperated yet.

Which would you use, why?
