Guys I have a Robertson Vision 66" 55@28, locator grip. I know it's not made any more but what other bows out there come close in design.
Their new model is the Primal Styke LB, with bamboo core. The handle is a locator, and about 4-3/4" circumferance at the narrowest part of the handle, and 5-1/8" at the heal. The 64" bow has a moderate reflex-deflex, smooth drawing, and shoots great. The limbs are similar in taper, and a tad narrower at the nock than the same weight Purist in a 62". Very similar otherwise. I like the bow.
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. :)

I like the looks of the Liberty Contender,it is a mild R/D bow.
There are a bunch of fine mild R/D bows out there, I would guess the closest to the Vision would be the current Robertson offering, The Primal Styk.
