I put on the 12oz. weight on my 2004 EC300 and love it. Tried it for the first time today and tractored around the trails with much greater throttle control than I've had in the past. Didn't notice any lagging in the taller gears and the low end was a dream. That combined with my rekluse clutch and rear brake on the left handlebar made it seem like I was riding a motorized and nimble mountain bike. I'm hooked!
