Ho boy...that's a toughie.  IIRC, the Missile was similar to the Sapphire Zone (and the Parker Bohn MVP), but the cover was tweaked for more length.  About the closest thing that I could think of in the current Big B line is the Monster Bruiser, but the Bruiser has a stronger cover and a higher RG core.

I seem to recall that someone on this site was selling a Missile not long ago.  There may also still be a few out on eBay.  Worth a look, perhaps.

Hope this helps.
