You bought it. Use it however you wish.
From a builder's point of view, I feel my shafts are better & are a perfect match for the butts I build. If I honestly felt that aftermarket shafts were better, i'd save myself the grief of driving a trailer to Michigan twice a year for maple & then the years of cutting to complete a shaft. I'd instead just install aftermarket shafts. But as of now, IMO, there's nothing yet that can compare to a well made high grade maple shaft. I'm no idiot. If there really was something better, i'd be using it. I could build more cues faster if I could just install pre-made shafts.
That's all said as my own opinion. Everybody has their own. Don't be afraid to try things. And be fair to yourself & give everything a solid chance with no bias. This will be the only way to really find what you like, whether it be a solid shaft or a laminated low deflection shaft. Choose what works best for you. It's your game, why should it be hendered by somebody else's opinion?
