Yes i know the sweet potatoe is kinda similar..but also quite different perhaps the biggest difference the biscuit/gravy have same front and tail measurments and a thruster set up, plus the gravy is more refined.

Are there any plans for something more similar to a biscuit/gravy?

I had a gravy and it went great i would have kept it, but every surf it just seemed to get more and more dinged up...so now im not turning back, its fw only from now on in, im stoked on firewires there light, they go but they also last.
