Robertson changed/tweeked the amount of R/D in his longbows over the years, and changed the names even more, though his basic longbow hasn't changed that much. The vision is similar to the purist and mystical before it. All are still available on the used market, and, of course, Dick will build you a new one.
The Liberty Contender has a very similar R/D design, maybe just a little less reflex. The Chief elite, has more R/D and is similar to some of Dick's longbows, though probably has just a tad more reflex than the Robertson's. I don't know if Allen is still building the Chief elite.
The Great Northern Critter Gitter is also similar, though it has just a smidgen less R/D than most of Dick's bows.
Rich Wormington's Yellowstone has the mild R/D of the Liberty Contender and GN Critter Gitter.
They're all excellent bows. Probably a few more out there that I neglected to mention. Good luck.
