The fly great--right with my field tips, slicktricks and wacems! I've got deer, elk and antelope hunts this fall. Hope to compare the turbos and wacems with the slicktrick which I like very much. The turbos clearly have the sharpest blades. Shooting them into a foam targets, its clear they twist upon impact. Don't know if its good or bad--just something I noticed. I'm excited to compare results--still not sure which heads I'm going to use for which species. This is a wonderful dilema.
