ok...got one last question (hopefully)

its time to get a new speedo for the cleveland race...what should I get? been running a gt-7 and its too big to find room for a receiver pack running a low profile body (trust me...its too big lol!!! ) I was looking at the GM sx-9...masami won the worlds with it...cant be too bad...but I guess he can drive anything and win. Also looking at the new quantum comp. or the ko speedo Chris Doseck used in his spashette trinity car. Lemme know what you think I should go for.
