1. Centaur (Jim Neaves), especially the Chimera or Double Carbon: combines all good features in one bow: ultra smooth to draw, fastest bow I shot (except Saluki Ibex), very stable though they are short and very maneuverable, perfect handle (that gets customized to your hand), exceptional nice bowyer that makes your dreams come true.
2. Bigriver (John McDonald): simple appealing design with very good shootig characteristics, reasonable priced
3. Lightning Hunter (Gordy Morey)
4. Border Griffon GL (dunno if this is the kind of R/D bow you where asking for): look what Pete Ward wrote about it
