Oops just realised the title might not give all the info. It should read dest210r and not probably what everyone thought - dex210. Sorry for the confusion.
Fernandez: Thanks. I am hoping that the heavier weight of the st's front end might reduce the lightheadness of rm4
Origineelreclamebord: Thanks. That shows I haven't really worked on the chassis enough. Now on the fence of reconverting back. OK, maybe after trying rm4 first.
