try asking James on NS about trying to drift his 4 door 32 wt td06 25g (he bought the kit of the guy in the hpi write up) from what he has said to me its lag city
It all depends on the track your going to be drifiting my 2530 makes my life hard going around Port G as its such a small track.
On a track like Mallala I'd probably be very happy with the 2530
just remember to do lots of limiter clutch dumps works for me
