Hi all. I've been reading up on reed valves since I'm going to replace mine soon. This is for a '92 WR200 that has the original reeds in it. From what I have read here it sounds like a dual stage reed would be good for me, need a little more power on the low end. I see Boyesen makes a 'power reed', 'super stock' and a few others. Which one is a dual stage, each catalog and web site that I go to says different things about them. Chaparrel says the 'super stock' is a dual stage but denniskirk says its a single. DK says the 'power reed' is a dual stage, which one should I get?
