G'day Stu, sorry mate i was refering to your earlier post when you were considering which way to go. take the misses out and buy her some new shoes and tupperware (they love that stuff, mine has every known container in the world) and then tell her you reckon you will keep the 500 as an investment, job done.
I have a 2005 300exc and i have tried the springs, they do make a very noticable difference, i prefer the standard one as i only use mine as a trail bike. the light spring makes it like a 125 to me and the heavy spring would be great for those muddy days of yesteryear (hopefully they will come back).
