I do the same as nchawkeye. I shoot NAP thunderheads. I have a few heads that are just for practice. After I am happy with my groups I shoot the heads that I will be hunting with. I do this because all heads,even though they appear the same do not shoot the same. Once I have the heads that I am happy with, I change the blades and place them in my quiver ready to hunt.

I also shoot the arrows that I will hunt with also. I have one arrow that I have harvested 5 deer with. I will keep shooting that arrow until it does not fly well or until I break it!

I would just replace the blades in your slick tricks. Unless you are just honing them, it is a waste of time.

If this is the first time you have hunted with slick tricks you will love them. They are good heads. Confidence in the heads you hunt with is everything in my opinion.
