There are a lot of good ones and if your broadheads are mounted to spin true and your setup is truly tuned,any should fly well.
If you are mounting glue on heads I would highly recommend making a spinning jig.Pictured is the one I use but you can make a simple wood one with V blocks instead of rollers.This is way more precise than the way I used to spin and eyeball them.
The tuning method I use is found at
www.bowmaker.net I'm currently using 200 gr Grizzlies and they fly very well but have to be mounted properly and tuned.I recheck for spin after missing or hitting an animal.
If you like screw in broadheads,there is a thread on the new one by VPA.It is CNC machined out of a solid bar of steel and they are known for high quality.
I would bet you could get those Zwickeys to fly really well if they were spinning properly and tuned for your bow.
