Hi guys, we are not allowed to race the Speed 8's ro 12's here in the UK so most people either use the Zytek or HB Raynard. I personally like the Protoform Speed 12 shell (see pics) and although not allowed in our Nationals, we can use them in our own winter series. I also liked the Protoform Speed 8 b'shell but they are not availible anymore. Cheers, Chris.
