Id say with Cen dont put all your eggs in one basket, I started with a Cen MT2 and then bought a Savage and I love them both but wouldnt buy another MT2, maybe the Magnum will be better tho with the upgrades Cen has made.
IMHO the Savage is built better but the Cen is easier to work on, and the Sav can take the knocks way better.
And if I bought another truck it would be a Losi LST2.
Thats my 2c.
