Envy Carbon Fiber Brush

I just received a one off Carbon Fiber Brush from Nathan at Envy. 

I've seen Envy Shave's handles online, including the carbon fiber ones, and they look very nice.  Unfortunately, the fan shape and high loft on the Envy Shave synthetics result in less backbone than I prefer.  If they release black synthetic bulb knots set to a lower loft, I would definitely consider acquiring one.
