I know that we are not talking the TQ but the TQ use to be the top of the line before the EC cam out. OK now I was running the Georgia Championship Series yesterday that Ryan Lopez runs who is factory sponsored by Xray. He said the EC handles MUCH better then the TQ did. Said there is a night and day difference. So I am sure the EC handles much better then the R. But I am sure both are very good buggies. If I had the money to buy a new buggy it would defiantly be the EC.
