I prefer woodies but understand a smaller diameter aluminum or even smaller carbon would go deeper with the same force. Straight forward physics - icepick versus dowell. Smaller- has a LOT less friction and less "work" - muscle and/or hog "toughness" to separate.
Why doesn't anybody -insisting on sticking to woodies and older like me and shooting lighter weight -47-48 lb range - an knowing lots of hogs will be seen- or wanting to hunt hogs- grease up the spine to compensate? The standard answer is everthing smells and it will screw up the hunting,go to a heavier bow. I know I could shoot more weight,but that raises other problems,one of which is accuracy,with a short drawing fault,and snap shooting, another is sholder problems. I'm 67 years old.
Are there some non-smelling choices we could use and does anybody here do that?
