From what I have been told recently, keep in mind I've never changed reeds in anything didn't believe it made a big enough difference. (DASA intake) Vforce 2's are T/R, more low end. (DASA intake) 3's are T/R and top end (racing). (BOYESON intake) RAD valves are the best for flatwater. I'm not one to speculate on reeds, I know engine builders recommend what they want. I ordered a Vforce 2 setup from thrust, they sent the setup directly from Dasa and I received Vforce 3's instead. They offered to exchange them but I opted out. Not that big of a deal for me. I would check if there are any other mods you can do for the same amount of $ that are more of a gain. JMO
