I am not a great expert on this matter, althoug I shoot ocassionally barebow in competition, but if You want I can ask the silver medalist from European FITA champs and also World games in Japan. He is a friend of mine and is called Žare Kranjc.
As far as I can see, people in my country are definitely moving away from Hoyt risers, especially from Elan. The most popular seem to be Spigarelli and Greenhorn risers (they both have special models for barebow).
