First came into contact with B3 at Old Trafford at the Cricket Expo... they had some pre-mades and one was a gorgeous retro shape, thinner edges and shoulder, spine right down to the toe, lovely shape, similar in some ways to a Hunts County Clipper. Wish I had bought it now... However, I assume any bat shape can be designed and constructed through CAD technology and with some of us older players always having one eye on the past, maybe a B3 Nostalgia range would have some interest...
I once batted with a Magnum, the chocolate coating soon cracked and then the ice cream fell off the stick.
