From who?

There's an argument for and against epoxy boards at the upper end of surfing, although mostly it comes down to preference.
At your level, epoxies only have advantages - they're tougher and they're (often, but not always) lighter.
So don't worry about that just yet (or for the next 5 to 10 years or so). The measurements look about right to me, but I know diddly squat about longboards so I'll let someone else chime in.
