Lighter eh? When the JRX-Pro came out, I started running 7 cells flat everywhere - even in stock. On a lark, I accidentally left my six cells at home one day and had to improvise. The car handled much better with the additional weight, in effect, I used ballast to help rectify the spring unbalance. And my world got a ton easier once I ditched the 5 link.
Sorry for the hyjack.
