Do what works for YOU!
Kaci, with his second World 10-ball title in the past 3 years using a wood 314-2, says "hi".All I know is the top 4 players (Gorst, Filler, FSR, SVB) all use Carbon Fiber!
And Filler got to the top of the fargorate list using a woodshaft.
Your ignorance is delightful.
Again, I'm not anti-carbon fiber. But wood works well too.
